I have been using it from version v0.5.0, and I can say it is well maintained and user requests are heavily considered when it comes to its development, something not true on how Evernote reacts, when we ask for something. Plus, it is from the dog* who made signale, so it is going to stay of good quality.
* Apparently it's not actually that cute dog who made it.
But crazy how americans pay to go to university. In majority of Europe we take nation wide exams on the last year of high school, on subjects like math and physics and if you study hard and score enough you pass, very difficult to make it in some schools though due to enormous competition. The advantage is that unis are free since people pay them through their taxes, ie germany, switzerland, greece (ece ntua), sweden etc
