Well, okay. That’s a lofty claim. The author himself says:
I know what you’re thinking. You’ve already seen 15 best WordPress plugins posts this month and you can’t possibly read another one. Trust me, I feel your pain. It seems like every popular website has some arbitrary list of the best WordPress plugins of 2015, 2014, and 2013, on their blog. The thing is, most of them are totally full of crap.
It’s true. You see a bazillion posts like this. But this one is very helpful, because it rates plugins in terms of the quality of their coding. That’s the main problem with most WP plugins–they’re badly written, which means they break. And there is never a convenient time for a plugin to break. It’s always a huge pain in the ass.
