One thing you could do Michael is check out PostRank.com and submit your feed for analysis. ONce they are done, you can find all the posts with the highest "engagement" – based on some super secret algorithm they use that integrates comments, traffic, FB and Twitter shares, Google Page rank for key terms for the post, etc. No need to install anything on your blog either. I used to use it find the "most popular" posts for NMP – they have a widget you can install – but I hated the way the widget looked, so I removed it. Even still though, the services is very good at finding a short list of "good" posts.
My recent post Exit Through the Black Door

Thanks for the advice but I actually prefer direct reader feedback.

I thought this would be easy, but it's taking me longer than I expected… This sunglar poster here is really great! (WINK!)

Vote cast.

Heck! it took me a long time to traverse all them posts 😉 but on the upside I found a few ones I haven’t actually read on the day.

To choose only 5, even concentrating on the longer, “feature” like articles was a tough one.

In the end I picked 2 of yours and 3 by Roberto 😉 If it was 6 choices it would have been 3-3 ;).

To be fair I could probably easily pick more including the whole team, but hey a limit is a limit.

Many thanks and keep it up guys!
