When Linkinus first came out, it all looked quite well, support was nice and quick, development reacted to problems and bugs nearly instantly and even included innovative new features.

But after some time, development slowed down, and after the 1.3 release in May 2008 it came to a stop, or so it seems. Blog updates were promised, but nothing happened, The 1.4 update's release has been moved forward and forward and forwand, until now there's not even an expected time of arrival anymore.
Additionally the public bugtracker has been shut down.
On the IRC channel there's talk they are working hard on the update, but that talk has been there for quite some time.

As it stands now, I can not recommend buying linkinus. Go ahead and try it out, but I wouln't advise on spending money on it until it's clear if and how it will move on.
