Today, I find not a lot has changed, except the sites where I used to go to find tablature are now charging for the same material.
I'd like to pay for quality transcription of music (like the official music books) but available online or in an app.
I have been thinking about implementing a github-style website for tabs but it seems that the interest for tab sites is slowly fading away.
Really think it's a dumb move to sue people for putting out tabs, but there you go .
But maybe you never found the alternative, which was a program that was basically a midi player that display all chords and notes in timed bars and play the music, with all the instruments split up.
You always knew the quality was good, since you could have the computer play the track to check it out before practising.
I don't remember what program I used back then, but this looks like a spiritual descendant, though I am not recommending anything:
And no, I'm not ashamed to do this; I was one of the lots of guys that submitted gp3 in early 2000's by manually transcribing them; later these community-generated tabs were takend down (DMCA I guess) but I was dumbfounded when I learned that some companies were selling access to the tabs.
If you're of my age (I'm similar age to Troy Grady, 45), then the free cracking the code videos on YouTube are a good watch anyway - entertaining as well as the story of playing guitar that I largely paralleled (but never found the solution that he did, alas, until now).

It's free, it's like Wikipedia in that anyone can edit it (so crappy transcriptions get replaced eventually by better ones), it even plays the song for you. The only bad thing is that it uses Flash.
