Brent has a great write-up on BlogChat so I’ll point folks over there.
Basically it is time to put BlogChat out of its misery and free up some servers that have been providing this service for free for about 7 years. I still remember the first frantic 24-48 hours of development on this thing and the very minor revisions to put it into service. It remained relatively untouched for many many years and still works perfectly fine today. As Brent said “a testament to its simplicity”.
The service will be shutting down within the next 2-4 weeks so those of you still using it please find an alternative.
