Yes. It's not just you.
Steemit.chat is currently down, and taking a long time to load even the error page.
This most likely means we've become so popular that the chat server has been bombarded to a point where it can't handle any more.
Hopefully we'll get an update from @cass and @riverhead to what's going on. Once they upgrade their server/add more servers, we can go back to having some fun on Steemit.Chat
In the mean time, SomeguyNetworks is open to all cryptocurrency users, we have a dedicated #steem channel: Join Us
