Presence technologies

Twitter, Jaiku, Facebook, Kyte, Plaxo, Del.icio.us etc.
These are some new applications you might want to learn more about.

The only way to 'grok' these is to get in there and try it for a couple of weeks. Find some friends and do it together.

My id on Twitter, and Delicious is "jdorner".
On Facebook, just search for John Dorner. One of the advantages of having an uncommon name is that there are only two of us on Facebook - so far.

Robert Scoble has a good intro to some of these.

I'll be blogging about these and some others when I have some time to blog. Right now, I've got to go catch my plane.
