I found something related to or at the wordspy.com.
Social networking fatigue is appears when people are tired to register new accounts and create their adentity over and over again. It's of cause funny that there is already a word for it. But the reality behind that
word phrase is not so cool. Personally I'm also really tired to register myself in every web2.0 service.
That is one of the reasons why I have installed wp-open Id plugin. E.g. you do not need register on this blog for leaving some comment. You can just us your Open ID link. I think Open ID could be the answer to the problem. What do you think?
Further more I consider to implement some support for my Open ID identity on this site. I'm sure it should be possible somehow.
