I made this request a few weeks ago, but it takes a few weeks for Google and other search engines to show the kinds of results that might influence others to participate.
We have a search engine of DailyKos. We do not have a quality search engine of contributing bloggers to DailyKos. I think it would be useful - and relatively easy.
All you have to do is add DKSE0405 to your blog template. Sooner or later, Google does the rest of the work. Currently there are three contributing bloggers whose blogs are searchable by this term. That's not enough to make it useful. But if 50 or 60 or more did so, it could be a useful research tool. Want to know if someone from Kos blogged previously about Carlos Gutierrez? You could do a DKSE0405 and "Carlos Gutierrez" search on Google and find out. (Don't bother, no hits in this limited search)
Seems like a useful thing to try, at least.
