Just as annectdote, your blog site is kind of broken on smaller screens (tablet). The useless right sidebar covers almost half of the screen, and overlaps the content (only a bit more than half of it is visible).

And then there are many many users world wide who use a smartphone (small screen) and connect over GPRS or Edge (slow as modem). Bonus points when overblown sites with dozends of ads and trackers crash your browser on a mobile device, because it ate all your RAM for lunch. Every additional JS file is a pain. Tip: Keep the total JS file size below 300KB.
