Too many SE sites causes confusion
Having duplicate sites and tags seems obsessively organized, disorganized, or both. Could merge them all together.
For example, if I had a sql script in a drupal module that keeps a list of servers/dbs and reboots them if necessary. I come here to post it; Where to ? SO/sql, sql pg, sql oracle, database, Database Administrator/the same tags as before, Drupal Answers/same, Webmasters/same, Web Applications/same, Server Fault/same, on and on, By the time the time I'm done writing this post, someone has created 5-10 more sites related to programming, each requiring their own login and separate set of tags yet named the same as all other sites.
Looking at the stats, I see SO is probably the best place to go for visibility & collaboration (why else are we here ?). However, looking at the creation dates, SO was created first and I presume that it was created with tags. So is the StackExchange site going away from the method of tags and embracing separate sites ?
