I think the barrier of entry is just way too high. This particular app requires you to install it on your own shared/vps and host it yourself.. Mint was successful for this (haveamint.com not mint.com), but that was a PHP app which is a lot easier to deploy than Django or Rails.
Anyways, what do you guys think? People are saying desktop software is dying because the barrier to install it is too high. If that's the case, I don't think a self-hosted Django or Rails product will do well at all.
Thanks for your input!
