87% of my readers are using Chrome on desktop. This means that I have the luxury to care less about performance. However I just recently found that this blog has 56 (out of 100) points on Google's pagespeed test. That's not good. The report says that my Disqus comments are blocking the main thread for ~900ms. I want comments on my blog but I also want my users to reach to content as quickly as possible. So, after so many years using Disqus I decided to break with it and use something else.

Usually I don't write such articles but this time I'll share my story. I was going to fly from London to Bulgaria. The flight is two hours and a half which is (by my opinion) enough to get bored. When I was traveling from Bulgaria to London I used my phone a lot. I read lots of stuff for reactive programming, played few games, ate some snacks. However, for the way back I wasn't prepared.
