Not sure if this OPML blog is written by CELL (Liu Peng). I met Cell on 2nd Chinese Blogger Conference. We talked a little bit about his startup OPML.cn. (Read my blog of the conference.)

This service has been online for one year. Basically it provides online OPML file viewing and editing. OPML is used widely for sharing RSS reading list. Actually it can be used for sharing any resources, like this OPML presentation.

I learned the importance of OPML when I was playing with Dave Winer’s OPML Editor. But there’s still no killer application for OPML yet. That’s the reason why service like OPML.cn still not widely adopted.
