I disagree. Most code posted on this site that has no lang tag in the PRE blocks is of a C flavour. Having a few messages be colourised incorrectly is a better tradeoff than having the majority of code blocks with no lang tag be uncoloured - especially given that the colouriser came in only after several hundred had already been posted.
[Edit: and yes, a compromise is to have the default language set different for different modules]

I also suggest, and this is new, you automatically replace CODE tags by PRE tags as soon as they span a newline. Yes, I want PRE blocks to be syntax colorized, as the colors work well on the PRE's background, whereas they don't work at all (at least for me) on the CODE background (especially the blueish one in forums).

Interesting, but trying to outthink what an aithor is attempting to do often ends in tears.
However, for the forums it is a different matter.
Very interesting. I'll add that to the list.

I guess your list is actually a heap. I sometimes wish it were more of a stack.

It's an ordered queue.

Ever since I visited Italy I've found it very useful to be clear on what sort of queue I mean.

technical people outside Italy agree on calling that a "heap", not an "ordered queue" 
BTW: first time I visited Boston, MA it reminded me a lot of Rome, Italy. Car drivers over there seemed very unamerican.

Adding to Luc's suggestion, we should also remove one PRE(or CODE) tag automatically if it's followed by another one immediately. In Q&A, many times, people put PRE tag to code part explicitly (for second time) even though when by default code gets formatted by a PRE tag while pasting.
Ex:
<pre lang="cs">protected void SampleCodeSnippet(object sender, EventArgs e)
{
}
HTML presentation of above:
<pre><pre lang="cs"> protected void SampleCodeSnippet(object sender, EventArgs e)
{
// some code
} </pre></pre>
Above highlighted part can be formatted internally(i.e. remove one PRE tag)

You need to pay more attention to the discussion. We're not talking about the pre blocks. Those need to be colourized, where the colour adds a great deal to the clarity of the reader. By contrast, the code tag is for marking, as I said, usage of code within the article text.

Thanks for the subtle hint. I wouldn't have thought to specify lang="text".

I never said the FAQ article said the CODE block supported a lang attribute, i was merely pointing you to a list of attribute values for the various languages. 
I think some authors get mixed up when to use CODE and PRE and as a result some of the articles look too coloured.
Agree that only code should be colourised using the CODE(for single inline statements, parameters, function names etc) and PRE for blocks of code.

Oh. Well, thanks for the heads up, but I actually did give it a cursory read before I published my article. A good thing, too, because I was initially colorizing the code within the pre blocks using the CSS classes. Manually.
As for InTouch, we often don't get to choose. When we do choose, we go with Windows Forms. But sometimes our customers buy our furnace and insist on integrating our Level 2 HMI within their existing SCADA system.

Silver members and above can edit that article. I've gone and added the magic few words.

I've gone back and forwards on this a few times. I'm leaning towards removing it again.

The inline coloring seems useless much of the time. One of the editors did that to one of my articles and I felt it reduced the quality of the article. I could have changed it, but of course that becomes more difficult once an editor gets his/her grubby hands all over it. It can be useful to color code (or, say, italisize) code when it is needed, such as when emphasis is desired or when the term is ambiguous. But that doesn't always apply. For example, it is common practice to uppercase SQL terms when writing SQL code, and that's a practice I carry over to articles. Emphasizing that additionally by adding color is just too distracting, unnecessary, and purposeless. Especially if the article is already broken into small chunks of text with lots of PRE blocks (with so much emphasis, where's a reader to focus?).

I don't mind a single distinct color for highlighting .NET class names, C# keywords, or identifiers that should be taken literally and not be confused with the regular English words. So a teacher can explain about class and Form and bool initialized in class.
Unfortunately I had to add a lang="text" twice to get the above CODE snippets all in a single color, otherwise it would have looked like this:

Agreed. The former is much nicer looking.

2x12=24
1x12=12

I understand. I went back and forth a couple times writing the article. In the end, I remembered something I learned about typesetting from the perspective of an editor: four fonts and two colors is enough. (Fonts here includes weight, point size, and italics -- extremely minimalist.) Any deviation should have a compelling justification.
The reasoning is that the article should allow the reader to focus on the content, put them in the zone. Any deviation at all (including the four fonts and two colors) draws attention at the expense of pulling the reader out of the zone. (Note this doesn't preclude more, it's just that when you see more you should consider it the editorial equivalent of a code-smell.)
I'm not saying that this opinion is right, but I've never heard a compelling contending argument. Hey, newspapers and magazines were successful for hundreds of years -- they must have learned some useful lessons.

My feeling is that the "two colours" rule doesn't always hold, especially for technical content that needs to be visually broken (eg comments and code).
In any case, colourisation for CODE blocks has been removed and I'm hoping to do a final test and upload today.

Your colourizer is stumbling over arrays.
Private Sub InteropIsothermControl_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
Dim IsothermColors As Double(,)
If Me.DesignMode Then
IsothermColors = New Double(,) {{0, 0, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}}
Else
IsothermColors = IsothermDataProvider.GetIsothermTemperatures()
End If
Check out the spans on the zeros. Only the last in each row is properly colourized.
