Is it worth it to upgrade? Or are forums dead?

[egexperiment626]

Currently, I am running VB 3.8.4. That's the highest I've been allowed to upgrade because my license expired in `09. My forums were fairly slow in volume and I had shut them down for all of 2012, to focus on other things. I've since rebranded & reopened and while one or two people are visiting, most are into FB, Twitter, and other social media venues. In fact a few times even I've tried to "like" a post on the forums, which clearly I can't do on my version. I almost feel that not being integrated in anyway with FB is causing people to not sign up, no one wants to have to register for another account. And yes, I am very aware that the year long shutdown hurt and I 100% know that is all on me. But I do wonder if lack of "updates" is also a tad bit of an issue.

So here is my question... is it worth it to spend the $209 to upgrade to 5.0, where I can have options to integrate with Twitter, FB, and more modern outlets, or should I just consider the forums a dead duck and put them out of their misery for good? Are message boards in general dying out do to social media outlets?
