I’ve used it for a bit. No real “catch”. The only issue (if you can call it an “issue”) is getting anyone that I would want to use it with to actually use it. Most of my friends aren’t “techy” on this level and don’t see the value. So my retroshare is basically me and my one other friend who I can get to use it. :)
Just chiming in to say that I’d be really interested in a magazine like this as well.
