As someone who has played on IoJ since BWE1, I can wholly recommend it.
We don't always win in WvW, but we do have a blast, and the community (both in and out of WvW) is as good as any other server. I saw some folks from Reddit, but they were not rowdy or obnoxious like others are hypothesizing.
I played on Isle of Janthir since BWE1 with my guild The Guardians (if you know us & or want to join your welcome to apply)
We did very well in WvW & had a very good community.
Frankly good doesn't even begin to describe it, just about everytime I found I needed help killing a high level mob or needed a rez in WvW I got one from some random person or a guild mate.
I also ran into a decent number of Reddit people and they were very nice. I even had conversations with a few & we helped each other on a couple quests.
So I would say that IOJ should be a very good server to try out. If you don't like it the first week or so after launch you can always leave.
+ if you decide to leave within the first week or so you probably won't be charged anything as it should take several for the servers to settle down & arena.net to change it over to paid transfers.
