Is there a way to merge some tags. For example, there is an 'adsense' tag and a 'google-adsense' tag. It would make more sense if they were one tag. There are a few other tags like that, but cannot think of them at the top of my head. Just offering the suggestion.
I agree. We can make synonyms for tags which is something I've been meaning to do myself. If you could help me make a list of duplicate tags like the one you mentioned I'll be more then happy to go through them and make synonyms for them.
If you feel that tags should be merged -- great!
Just open a meta topic here, or answer the existing one, and we'll merge them.
It is also possible to propose synonyms if you have 2500 reputation and at least 5 votes in the tag you are "synonymizing".
