There is now the possibility to add more than 5 tags up to 10, that should be enough for a great categorization.
I didn't know that! I hope SteemPeak might be capable of that function at some point. :) The 10 tags make it more enticing to post on the tribe front-ends... to be honest though, sometimes I struggle even coming up with 5, haha. The tribe-tags have been a very welcome addition in that regard!
