In a post on his blog yesterday, Dave Winer said:
The PubSub site is still up and running as I write this, looking as normal as it did the last time I visited a few weeks ago. No announcements there.
Mind you, something’s up – note PubSub CEO Bob Wyman’s advice in his blog on June 15:
Please be aware that in the very near future, it will be necessary to access this blog as: http://www.wyman.us/
Perhaps one indicator, here at Gnomedex Bob Wyman has scratched out PubSub.com from his name badge and has written in wyman.us.
So the end does look nigh. Wyman’s at least.
