I found out of PC Worlds top of 25 sites to keep an eye on via Sorin. I took a close look at some of them and here's what I found to be interesting or useful when spending most of your awake time online:

Wayfaring allows users to create maps for events, trips, day to day routes etc. Maps can be shared and viewed by other site users.

Swivel is the place to go for any type of research results, with graphs as a twist. It can turn out to be pretty useful for projects needing data.

Clipmarks is some kind of Stumpleupon with some cool extra features.

BlogBackupOnline is useful when your web hosting service or the free platform you're using does not satisfy your backup needs. It's a simple way to feel safer with your blog's content.

Approver lets you have certain documents distributed to an entire group to have them reviewed and approved.

Picnik is the site to go to when you need to edit a photo fast and have no photo editing software installed.

As you can see, only six of them. But take a look at the whole list and select your own favorites. Happy surfing everyone!
