Flickr is a great place to look around and get inspiration. Join a few groups, comment on some people's photos that catch your eye, then post your own photos. It starts to become quite addictive, posting your shots to see what the world thinks of them.
If you're feeling really keen join this group
Flickr: Project 365
Basically take 1 photo of anything you like every day for 365 days. It's quite a challenge but really gets you thinking about your camera and the shots you would like to take.
Oh, and have fun
