I get a magazine called acoustic guitar and every month they ave about 4 or 5 songs all in tab. Its a nice way to attack a song. Right now I am learning a finger picking song and its tough since i was never a finger picker...the lessons here are helping me with that to take it at a nice slow pace.

In my opinion...if you like playing the guitar...whichever way you are able to learn and get from point A to B is good....
some read music and practice 5 hours a day
some learn by watching others
some learn by playing tab
some only learn by what they fiddle around with and experiment on their own
whatever works for you and fits your goals....whatever gets you to play!
Good luck
