I've been experimenting with many web 2.0 services lately. Each one of them requires its own username and password. Admittedly using something like Hellotxt allows one to setup a service and then blog/update from hellotxt, so updating isn't that problematic - even though you aren't fully utilizing the service you signed up for because services like hellotxt and ping.fm allow you to use the lowest common denominator of services (i.e. text)

I've been thinking that I have way to many logins for all these services. I really wish that I could use openID for all these services - it would make life so much simpler!
