In theory I really like the economic model. By ensuring a revenue stream outside of ads, it should mean that we get the polish and longevity of a commercial product, but without having to pay for it (either with money or by giving up our privacy).

In practice, though, I wish it were more stable, with basic working features. Instead it seems like basic functionality is buggy[0], and major breaking changes could crop up at any time[1].
