I love Sphere!
Sphere helps me keep the conversation going after I have written a post, it rocks.
After I uploaded my post on Ovi, I "sphered it" and found some great, relevant content. I found the video below via Darla Mack, the Mobile Diva. Through the Diva I also discovered Twango which I am now signing up for and will report back.
Anyhow, have a look at this video about Ovi.
