Sure, I get it. I mean, what are we -- a bunch of experts at organizing information, or something? 😉
(I keeeed, I keeeed!)
If anything, this is one community where people truly understand how hard it is. Tags can help, but there's still a lot of untagged content. Is there a search syntax for tags, distinct from searching body text, like at SO? Even if there is, you still have to know the magic incantation. How many times have I searched SO for tag [SSAS], only to find the content I'm looking for is under [SQL-Server], or similar?
There's no easy answer, but thanks for the thoughtful responses. Maybe sometime you could engage the community in an open tagging exercise. Crowdsource the dirty work, I say.
