What are the main concerns people have about using evernote, data protection, the company going out of business, the code being closed and proprietary? I can understand all those but sometimes it also feels like everyone (me included) expects every software to be free now. I have a free evernote account and don't use it very much but I find it handy for some things such as cooking recipes and walking maps. I think it would also be great for Dave Allen's GTD technique if I could ever be disciplined enough. If evernote removed the free tier I think I would pay up, the pricing for the personal plans is very reasonable. I'd probably make more use of it too. Humans don't tend to value free stuff. For someone like me I think they'd have had a better chance of turning me into a paying customer if their model was an initial free period followed by having to pay up. But I will never pay up if I can get away with paying nothing.
