I'll send a proposal and then you guys can tell me how to proceed.

Apart from the various misspelled words I'm merging all the tags that seem related to the same things, like:

jboss5, jbossas7, jboss as 6 jboss as 7 => JBoss AS
orm, orm43 => Hibernate ORM
Seam 3, Seam 3 News,Seam Forge, Seam News, Seam Wiki => Seam 

Or do you think is too extreme?
