OK, having a 100 "friends" at facebook is nothing special. Even I have now 100 "friends". Nothing special so far, but I did not add a single one of them, they all added me. After being forced to open a facebookaccount a half a year ago, I decided in a silent protest to use it, but not add anyone unless the send me a request. Unless other networks I add just everybody (as long as he's not a real spamer with hunderts of contacts).
I do not like this crappy, spamy applications which do go in my way and in the one of the usability in general. But it's incredibly how many people do have a facebook account. There are not only the usual suspects (like my internet-save nerd friends) at facebook even my friends from primary school seams to have all an account.
I just want to let you know that facebook is absolutely crazy, no matter if you like it or not. (And for the geek in me, I think I can not help me and will lose a lot of time soon with there puzzles)
After years of archiving every mail I did get I changed the tactic last week. I do not archive anymore spam, most ad mails and auto-generated mails. I thought that saving all mails would probably help me one day to train my mailfilters. But now (a bit "technologie-lazy" in my spare time currently) I decided that a fast click on the delete button is much faster then everything else and let my have a bit more email efficiency.
