What has happened to Interchange support?

It was in 2001 that I first started using interchange and appreciated 
the multitude of replies to questions and queries for assistance. 
However, it has been noticeable to me that in the past year or so that 
responses have been fewer, not only for my posts but others as well. 
Have the ones who long supported this amazing e-commerce product just 
left and gone on to other products or concerns? Or possibly some other 
concerns?

Either way, it saddens me that it does not appear to be the flourishing 
community that used to be present.

One of the side effects is that I see fewer new independent sites that 
use Interchange. Or perhaps I have just missed seeing them. I do see 
some sites that have been developed by EndPoint and a few others, but it 
is the independent sites that seem to have reduced presence?
