International networks

It is interesting to see how several international on-line networks have organised their structure. I am member of LinkedIn, XING and Ecademy.
The one I use most is LinkedIn because of it (in my opinion) clear structure and businesslike layout. However I am always curious how a network may develop and there could be interesting details or widgets in other systems as well.

Most interesting is to see how socializing moves rapidly from Real Life to Virtual or On-Line Life and back again. I now often meet people I have met through the Internet.

While at one hand people are getting more concerned about their privacy (and so they should !) on the other hand they are showing the whole world what they are doing, eating, thinking and buying. Amazing isn't it ?

Me ? I lik gardening and the weather is okay today, so bye bye On-Line world, i am going out into the Real one.
