There are a lot of musicians on the internet now making names for themselves. It's really hard to know exactly how many are actually posting either videos or audio clips either of themselves solo or with a full band.
Myself, I haven't really done that at this point. But one person who has given me inspiration, not only to post a video, but has inspired me to play more than I normally do. This gentleman is talented and has an amazing personality as well.
I'm sure there are a lot of guitar player here who already know who he is, but if you don't and you happen to surf www.youtube.com then look up riffguy. He is one very talented musician and very personable. Check out his videos and leave him a comment if you can.
 You won't be disappointed watching him light up a fretboard whether he's playing a Fender Strat, Gibson or Epiphone SG and LP models or even just banging around on an acoustic. You'll even drool over his triple Marshall stack setup!
There is a sample below, check him out!
