Tough question to answer as "stinking" is a subjective term. I've been at this for 4-5 months...I've completed GF 1 and 2 and have started to Blues section....I can do most of what I've learned reasonably well, although Barre Chords are still very difficult and I expect they will continue to be for a long time. Having said that, there are TONS of songs out there to play, even without the Barre chords (I only play a few as I've spent most of my time on technique and am really just starting to play songs, but IMO that is a choice and one could spend more time on songs).
Most people will tell you alot of your progress depends on the time you put into it....I play almost every day for 30-45 mins, some days more and some days less. Personally, I am trying to just enjoy my practice sessions and trying not to focus too much on how far I progress...anyhow, good luck with it and have fun.
