Bought it a few years ago... and I wouldn't recommend it. It was created in a pre-iPad/iPhone era and it's not comfortable to use from anywhere else than a PC.
The problem is that reading their website it seems like it does not support multiple users? If I am going to self-host, I'd rather do it in a way that can support my family and friends.
That's true, but you'll have to recommend something as an alternative instead, since there is only a finite amount of RSS services; I say that as an RSS power user.
