Sorry to hear. Yes it started having trouble late last night I noticed. Things weren't displaying properly and a few upvotes I was making weren't recording either. I googled it and it has happened before. It's a new platform, still in beta as we all know, and growth pains like this are to be expected I guess.
Again I'm sorry for you. I'm drafting all my articles in separate docs, and am even considering doing so for comments. It feels like such a waste of time and a big gaping hole in your stomach when that happens, huh?
