It is also an ad for Request Metrics it seems. First thought my blockers let the ad through, then noticed the beaver in the other screenshot (reading from mobile now, so cannot view source). I've become so used to never see an ad that the animated ad image was a real surprise to see.

It's not immediately noticeable that it really is an ad for Request Metrics, but looking at their Twitter page makes it painfully obvious that it's a sponsored post:

Edit: actually, seems the author of this post also works for/owns trackjs.com, who owns requestmetrics.

Sad to see David Walsh' blog this way, of hidden sponsored posts. Really wish people could stick to ad-free principles better these days.

How exactly did this get on the front page? The webpage itself is a mess and the article contains nothing of any substance whatsoever.
