well, that is hard to answer. it depends what you like. here are some sites that might help you figure out what you like:
watchanimeon and
myanimelist dot net.
Death note and Gankutsuou are good shows.
fruits basketchibi vampirelittle princessskip beatprimo passo
naruto inuyasha basicly stuff like that i guess
"His and Her Circumstances" (Karakano) "Ah! My Goddess" "Chobits" ... to name a few that I enjoy. :)
I think that a group blog about anime would be a good idea. I have trouble finding good animes to watch so i think if we get loads of opinions then shows will be added and people can always have animes to watch.
Shotalicious.org is a good site that shows Shota and Yaoi (or "Gay") anime for free. No signing up, either. They're even showing Junjou Romantica, updated every Thursday, among other good yaoi anime. The site also offers pictures, as well.
Their are a couple of anime shows with all girl bands. Here are some good ones: K-On, TMOHS, Kannagi, Myself Yourself, Rosairo + Vampire, and Angel Beats
you can probably find some good PG anime on any anime channel
Now and then,here and there . Is a very good anime series .
depends on what you want from a anime.
I would recommend Rave Master (or Groove Adventure Rave in Japan), or InuYasha. These are both a good way to get used to the way anime storylines work. Then, I suggest you move on to shows with darker themes like Fullmetal Alchemist or Blood+.
Wedding Peach is one. (I can't think of any others though).
