The thing is, that every time you post something dumb the 'cat puts a little furball on your cookie. When the cookie gets fuzzy enough, your posts get balled up in the input pipe. Sometimes when you open the site, you're so fuzzy that you only get half-way in the door. It's harder, of course, to get your newest idea "on the table" when you're just shouting from the foyer.

As Bill D suggests, sometimes exiting and reopening the site will get you in far enough for things to work. If it's really bad, it might help to log out and then log back in to get a new shiny cookie that doesn't have all that fuzz on it.

Sometimes, when you post, you may also get interference from a "collision" with someone else's fuzzy cookie. The fur on the cookies gets tangled and only one (or sometimes neither one) gets through the pipe. The 'cat recently has handled fairly heavy traffic pretty well, but collisions do happen and apparently aren't always reported as such.

A post can also be lost by another server at your ISP or somewhere along the line as the message gets handed on toward the 'cat. This should be rare, but can happen; although it should be extremely rare without an error message.
