Since I switched the feed over to springinfo, it has plummeted from 70+ subscribers down to 18.
I had a lot of very good reasons for switching it back.

The switcharoo was not an affront to you, nor some kind of statement. It was a response to stats tanking.
Also, when analyzing the SI feed, I can't help but notice this:

<description>Just another WordPress site</description>
You haven't even changed the default description yet -_-
When you have SI ready to roll, we'll switch it back.
For those who are curious, the lists of feeds being used are listed here:
