I dislike the caps. I'd go with a simple colon instead of the square brackets.
That would make it less visually jarring while still allowing quick filtering.
Agree; ata, could you retitle your post to match what appears to be a weak consensus for no caps and yes colons?
I propose the following title keywords for Discussion posts, to be included as I did with [META] in this one.
Feel free to propose others, debate the merit of the ones I've suggested, tell me that the whole thing is a stupid idea, etc.
This is not meant to replace the actual Tags system, which is good for arbitrarily tagging posts by topic. I see this as a way to allow us to quickly scan through the list of Discussions and know what general type of content to expect from each item. I don't expect that absolutely everything will need one of these keywords, but many/most of the things that have been posted in Discussion so far seem to be categorizable along these lines. And I don't intend by this to encourage specific types of content (e.g. if we get more polls as Discussion posts now as a result of having a [POLL] keyword, then it is not working correctly), I only suggest that it may be useful for organizing the things people are already using this section for.
