Jumpshare is terrific, I've used it daily for the last year. It's got several key features that (afaik) none of the other competing services have (the best is being able to disable download for shared content, which is exceptionally useful!—I use it for sharing homework solutions with my students). The business plan looks pretty neat too (although of no current use for me).

I use it for sharing lecture notes with my students. Very pleased. Pros: Easy to use, more powerful than competing products Cons: Looking forward to table support!

Do you have any plans to introduce the ability to *block* trackers? (Canary Mail does this).
