YOUTUBE AND MYSPACE

Only a couple of months ago I discovered these sites thanks to a few "chordians" who referred to these 2 sites.
Isn't it amazing? You can find almost everything.
- If you want a certain guitar brand ===> you can see and listen to that guitar sound.
OF COURSE, it is better to hear it in a guitar store.
- PRO = you are able to listen to an Epihone, Gibson, Fender, and other brands, even learn "how to  play a certain song, some guys explain it real good. Search, look and hear how to play the WORLD FAMOUS intro: SWEET HOME ALABAMA. Only one remark: even Lynard Skynard  or Lynyrd Skynyrd (WHAT IS THE REAL NAME?) play that intro different on stage. There is a dude explaining it very detailed.
- CON = it's not at all the "real" thing, talking about the sound of a guitar.
so:
- PRO: ability to hear different guitar brands + tutorial info about "how to play that song"
- CON: As told, an Epiphone on youtube sounds different in a music store, but again a PRO it gives you already an idea of the sound.
IT IS UNBELIEVABLE INDEED "THE POSSIBILITY" TO LISTEN AND TO SEE ALMOST EVERYTHING.
I use quit often these sites, TO HEAR FELLOW CHORDIANS. I RESPECT AND ADMIRE YOU ALL, FROM OUR YOUNG CHORDIANS TO THE OLDER CHORDIANS.
Q: is there a specific site, for us chordians to show our songs???
