It seems that my Twitter Updates are not showing up from Ping.fm

I've had this problem for the past several days, and it's driving me nuts. But the only advice I've seen so far (from @pingfm on Twitter) is to remove and re-add the service, which had no effect at all. Is there an explanation for this problem, and is it being addressed?

This happens to me like every 2 weeks or so. It just skips Twitter. But what kills me is that "Recent Posts" said it posted which, of course, is not true. So that accuracy should be fixed as well.

If this problem persists, it kinda eliminates the entire purpose of Ping because I have to go in and individually update all my sites anyway!! Geeez.

As of today (11-5-09) all seems to be well -- my post went through right away to Twitter and LinkedIn. Troubling that there seems to be no rhyme or reason to the challenge.

I removed both twitter and myspace (i.e. all of the broken ones) and the re-added the services... doing just one of them didn't seem to work. And it was after the second time that I did it started to work finally.... go figure!
