Welcome to GYF. Good luck!
If you're interested in starting a blog you should probably read
http://www.gofuckyourself.com/showthread.php?t=684514 if you haven't already. It's a nice little primer.
A blog doesn't have an advantage over TGP but it's a little easier to make it stand out over a TGP because usually they have larger images and some descriptive text to go along with the babes/dudes/acts. Usually less skimming going on too.
Good luck.
