I have really be getting into the guts of Radio the past couple of days. The object database is quite cool. It comes at database theory from more of a programmer's perspective than a normal RDBMS. It is refreshing, actually. I have been able to get tons of stuff into the database and I am not working on getting tons of stuff out and displayed.
I am working on a tool that imports instant message logs into Radio and allows you to post individual IMs or entire conversations to your weblog. I am using Trillian logs at the data source. I should have a beta out in the next few days. I will post it to the radio-dev list.
