I would think many others - including myself - are OK with the current parameters. In fact, I do not remember ever getting "timed" out even though I have been online for awhile... hours at a time.
One solution for you might be to copy your post (before hitting submit) just in case it does not take. That way, it would be in your clipboard... you could just log back in and paste.
Sounds like this is a normal problem for you....
