Though I had a late start when it came to watching anime this summer (didn't start until early July), I ended up watching 12 seasons before college started up, which I think is pretty impressive considering I actually have a job.
These were all relatively new to me, and I ended up loving all of them, with each getting at least a 4 star rating in my book.
In chronological order I watched:
Hetalia: Axis Powers
Ouran High School Host Club
The Melancholy of Haruhi Suzumiya
Clannad: After Story
...Yes, thats a lot of slice of life anime I got there...and yes, a few of those are shoujo..and yes I'm a guy who like girls....DONT JUDGE ME!!!!
Heh, but any TRUE anime fan knows and loves a good show when they see one - regardless of it's catagory!
