Hey Ray, thanks. I've tried chartbeat, gosquared, and google's realtime. They're all fine, but now I mostly just get it via twitter.
It's not "analytics" per se, but the first 10 minutes worth of retweets is a better indicator of whether a post has legs or not than anything else.
With the proper realtime tools, I would basically just watch for irregular spikes after I pushed a post. The actual numbers never really mattered.
A quick SMS saying the post was doing better than 80% of my other posts would do the trick too.
