Do you belong to more than three social networking sites? Are you tired of going to all three to check your messages and see who posted to their blogs? Now you don't have to anymore.

Profilactic, Profile Linker and Loopster have a better idea for you. Link all your social networking sites all in one place by using one of these services.

With Profilactic you will get all the things you add to your profile sites all in one place. They call it "Mashup" and it takes all your profile sites, and other sites, and puts them all on one page for you. You can also add friends and see their Mashups.

ProfileLinker takes all of your profile sites and adds them to a single place too. They also will notify you when friends update their profiles and if you get new messages. ProfileLinker will also let you search all your social networking sites at once.

Loopster lets you actually keep in touch with your friends through your Loopster page. Loopster will combine all your friends profiles in one place so it's easier for you to keep track of them all. Whenever a friend updates their site you will know because their section on your Loopster page will light up with an icon that says "New".

I had some trouble trying Loopster and ProfileLinker. Their sites were down at different times. When I finally did sign up with Loopster the verification email never reached me so I couldn't finish signing up. I signed up with Profilactic with no problems at all.
