Never really used it, but I still find it silly that we've lost more features than we've acquired through the change.
The inability to write Articles and Stories bugs me. I think I could cook up something good, but look at that - Articles aren't available anymore at all! Although if they add them, I hope they'll add the option to delete them. I did write some really stupid nonsense back in the day too, I'm glad those were deleted with the change - but still, no articles? Meh.
I'm kinda mixed on it. I used to get some really annoying people hitting me up for chat for ex-s/o rants and it got annoying. But I didn't mind some people. If they improved the chat a little that woulda helped though.
I don't really care. I rarely used the chat system back then anyway. As soon as I would log on I would just turn off the chat function because I would just have people messaging me just wanting to talk about sex or exchange nudes which I had no desire to do. I have no problems simply messaging people with the system that is in place now.
I never liked the chat but they should have kept it optional for those who wanted it. What I didn't like was that sometimes it logged on even if I didn't want it on, and I wouldn't realize it was on until someone messaged me. There should be an option to keep it off unless you decide you want it on. I'm actually surprised they got rid of it.
