I think Online Chess here at Chess.com is going strong. Doubt it will be going away any time soon.
I believe there are lots of people who see its value as a learning tool.
I know there are those nay sayers who talk about cheating. But, really, I think most cheaters would rather play faster games where they can get rating points faster.
Besides, so what if a few people cheat? The vast majority don't. And, if you do lose to a cheater, so what? If you are using CC as a learning tool, then you will learn something.
I wish you had not made your question so open ended. There are many who don't 'get' this form of chess and they will be around soon talking shit about it.
There have been some threads lately about correspondence chess and that made me think of something.
How is the future of correspondence chess going to look like?
In my opinion I think it will be more divided in groups, for example, no assistance, only books and databases and then computer help.
The last one I really don't like because what's the fun in that?
CC Chess is great if you ask me and I hope to see it here on Chess.com for a long time to come!
What are your thoughts on CC Chess?
