I'm real glad to see this on the HN frontpage and I'm kind of surprised that I didn't submit it at some point...I joined the beta just to contribute some material/upvotes so it could be approved. I honestly don't use it that much on a day to day basis, but having had used it, and occasionally answering questions...it does fill a real niche that regular Stack Overflow doesn't.<p>If you were to ask me before, I'd think that the StackOverflow would be good enough because many, many data problems are programming related (how to parse one format, database optimization, etc)...but there are issues specific to data, such as denormalization...not <i>how</i> or necessarily <i>when</i> to do it at the database schema, but why...or rather, given a set of data (such as from the gov't) in which normalization was obviously not done...what is the most sensical compromise that you should do in organizing the data?<p>Anyway, hope more people get into it...I've worked in data for awhile and now, having to think about it, it's definitely a big enough field with enough questions to justify a vibrant SE board.
