I started to work with social network applications on the web and focused on openBC first as it seems to be quite common here where I live. After some days I can say that:

• the free account is about unusable and the premium account seems to be far too expensive
• The Lotus Notes integration exists but is so bad I refuse to use it and declare it bullshit
  

There are alternatives on the web and I would like to hear if you can recommend any of them or others.

• Friendster
• Orkut (powered by Google)
• MySpace
