I would take this article a lot more seriously if it didn't have "tweet" buttons embedded inside the article itself.
To me the links looked like they were to related articles, in the way that every other blog does it. I actually stopped reading the article two paragraphs in because I no longer respect the professional opinion of the blog based on this practice.
This is awesome. The more feedback the better. Running lean startup on the lean startup blog.
Does anyone actually like the tweet buttons?
I'll relay this feedback to Tristan Kromer who runs the lean startup circle blog editorial. My guess is that they're experimenting with ways to increase engagement with both the article and blog.
