After 3 years of keeping the facebook account alive, filling it with information and winning several "likers" and "followers", we nevertheless finally stopped the use of facebook and quit.
Facebook became too much of a pain and was almost impossible keep it under control (with facebook changing rules every other month and setting defaults against explicitely defined rules).
Too much effort, too little value...
We are still active with Google+
and will add more and more content to the MegaZine3 blog
and the MZ3-Tool3 blog
(German Blogs: MegaZine3
Anyhow, thank you to all the "fans" who participated and followed!
