With Office Live and many new and old web services (aka web 2.0? I need another post on that...) like blogroll/Google reader/blogmarks/what not, I am still a bit hesitate to use these on-line services. You can say I am a conservative geek or a backward person, but I am really a control freaks that want all my data under my total control. Therefore, I prefer to run my own version of the service and re-invent the wheels.

why?
- Privary? maybe
- Availability, I guess. Services running remotely is subject to outage and down time.... yes, my server running all my data present is a single point of failure....
- I like to have a copy of all my data. Having them scatter around on the net is hard, even sometimes impossible to archive them. It makes me feel uncomfortable. Yes, one copy for all is also one copy to lost and if it got destroy..... I lost them all.... but then I need a secondary backup mechanism anyway.
