my concern is what load this will put on the server/site. Stratics has already been getting sluggish for many of us - throwing up new features should not be the priority. Getting rid of your old stuff and getting this "wiki" running should be numero uno imosho.
Get rid of the wordpress CMS installs. Archive the info, get it off the server, and migrate the content as quickly as you can into the CMS of your choosing (ie - here in xenforo).
I still think laying all your eggs into one basket is NOT a good thing, but that's just me.
I don't think people spend as much time on Stratics as they do on say, Facebook, to garner such a feature with the potential load it will have on the server/client and the bandwidth sucking it could potentially have. Shoot - I never turn on the FB chat.... it all goes to my phone anyway and if its important, I reposnd via such.
When I'm in game, I rarely open Stratics or any other website for that matter. I want as minimal load/feed/bandwidth usage on my computer - particularly if I'm going into something interesting (Eodon, Dragon Turtle Champ, Felucca, IDOC, etc.) and having ppl pop-up a convo on a website would just irk the hell outta me.
