Triggers have their place. Like Global variables, and the rarely used GOTO.
growing up in Oracle, every table with an ID column got a sequence, and a trigger.
A Concept that bothered me (vs the simplicity of auto-increment), but I was grateful for before the "OUTPUT Inserted.ID" could accurately tell me the identity of an inserted row!
We used them to log changes across multiple applications (web and various clients), and those logs were used to restore data that was accidentally "lost" due to human error.
But when I have the OPTION of limiting access to a single application... You don't have to have them, and you really need to make sure you are not just being lazy... Or making a system overly complicated!

336 triggers on 1450 tables... (~23%)
I never kept track because my coding responsibilities weren't close to the database but when I did have to work there I discovered way too much business logic in our stored-procedures and triggers. So much that it made diagnosing bugs extremely difficult. One of the stored procedures was a complex query that was so deep that it could take days just to figure out what the desired result set would be ... of course it was heavily commented (NOT!). I can't stand it when someone seems to intentionally write obscure, un-maintainable code.

I do not use them. I understand them. I understood their place back when databases often housed business logic in a client-server environment.
But - IMHO informed by experience - applications are scalable and reliable when databases are limited to CRUD operations, and business logic and whatever one once used triggers for, is placed in the compiled code in middleware.
Yes, it is easier to update a trigger, SP, view, or UDF since apps do not have to be updated. But as most can attest, the DB complexity mushrooms and performance is hurt.
Intelligent app architecture compensates for much of that.
My advice is to keep the DB to a CRUD machine, and leave the logic to the compiled code.

When I go to the CP home page the icon (favicon) in the Chrome tab is the twitter bird. Anyone else?

Nope. I would say some kind of Chrome's cache corruption?

That's what I figured but I don't ever recall going to twitter before so not sure where it would have picked it up from.

Nowadays twatter, fishbook, etc. icons are everywhere; you may even have a hard time finding a website that does not try to link to these social media accounts.
But as to know why this supposed corruption has occurred, I'm useless. Does Chrome have a clear cache function? Did you try it?

Mind you, the lounge has a blank page icon instead of Bob...

No, but I do see blank page icons sometimes, like on this page (after I clicked reply) and most QA pages.

It's not working! Should I blame caching?
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Ancient

Is the right answer - you are up tomorrow!
The "contains" bit is NE for "north-eastern", IC for chip, mixed up inside the ANT.

Cut the young'uns some slack; you have to admit that the term is a bit old-fashioned these days.
OTOH, I still "dial" a phone number, so what do I know? 
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.
