Being a 50's something I sometimes have a hard time keeping up with the ever growing new technologies out there. How many of you use things like Twitter, MySpace, Facebook, RSS? Do you blog or use social bookmarking (i.e. Delicious)?
If you use any of the above (or something I haven't mentioned) tell us about what you feel are the advantages and disadvantages.

I have recently started using social bookmarking on Delicious. The big advantage for me is that I use at least three different computers on a regular basis. This enables me to have all my bookmarks stored in one place and they can be accessed from any computer I am using. I have done some searching of the tags for other sites that other people have bookmarked and have found some new and fun sites that way. I am pretty new to the process and have a lot to learn yet.
