Mostly desktop/laptop browsers are significantly impacted, mobile users not so much.
I hope they are doing something about it, likely not as there really aren't any HF alternative sites out there.
Well, there's alternatives just not with the traffic this site has.
I used to visit a forum called Harmony Central, for musicians. Massive site. They decided to move on from vBulletin and it was an epic disaster and now the subforum I used to visit multiple times daily that had hundreds if not thousands of new posts a day is down to what seems like 3 or 4 posts a day. Basically they killed a massive community when they could have just stuck to what worked and appreciate what they had.
I really hope that doesn't happen here, and the easiest way to prevent that would be to just get the site working and not freezing or crashing and get some alternative themes out asap because the appearance is a turn off for most people. I think it's ok but a big step down from the old site.
I've sat down with the intentions of surfing these boards like usual and after a few freezes I just decide to go do other stuff, that's not good and the frustration will only get worse the longer it's like this (though it's been good today for me) and it will result in the community dwindling. It can happen surprisingly fast even to the biggest forums.
