rjbull,
that would not be a sharing method because first it is one way, second it takes alot of steps and dedication. IF you want to sync 50 items a day, that will take alot of time and resources. On the otherhand I can just save .mht out of FF anyways it is easier.
I have been using Evernote and was a dedicated fan for sometime but I have stopped using it last month because I realized that they actually do not care much about their offline users. They want more people to put more stuff on their online servers. I personally hate all these online stuff, online sync online storage. I like to take care of my own data my way not someone else`s way. Also subscription based models are deceptive. I cared about their application not their online options but they seem to like to make subscription based pricing and most of their improvement has been about online stuff. So it makes no sense for me to pay for their subscription. Anyways it might be a good model for those who are crazy for online storage options. To me its waste of time, money and resources to sync local data over internet. You can sync your local evernotes over the internet. But this is a problem it you have more than couple hundred megs.
