I think it could be viewed by some as a bit harsh. Maybe a better approach could have been to simply ask what the intended purpose was instead of guessing there was supposed to be a point you just weren't grasping? I do appreciate summarizing the pros and cons of things from a perspective of _actually_ trying to use all of them to accomplish a common goal though. I think they were just trying to not give a purely subjective opinion on their differences... and one could argue that this information might be useful to make one's own choice as to which solution to use for their next project. I didn't get the sense that they were trying to plug anything or drive traffic at all. I could also argue that merely linking to a blog post in the first place might be doing the same thing... but where should the line by drawn and who should the authority be on that?
