Two of the tags that I have set to "interesting" on stackoverflow are "perl" and "apache". I have a feeling that it won't be long until I remove the apache tag from that list because 98% of questions with that tag relate to url-rewriting with mod_rewrite. I won't do that with perl anytime soon, but that tag (sometimes) has a similar problem with questions about regular expressions.
These questions are dupes, but slight variations on the same topic. In fact with the apache example, it has become next to impossible to find a dupe because the stream of questions has become so endless.
What would be the best way to deal with questions like these?
