I am going to try to enumerate as many of the WordPress sins as possible (maybe to get it off my chest, maybe to have a place to point to when someone asks me what is my beef with WordPress) but it is very important to remember that everything in life needs to be measured in a context, otherwise all you end up with is just a pointless “holy rage” which might be cool when you need a reason to burn some adrenaline, but unless you are are religious leader or politician, it is very rarely productive in real life.
After all the things are said, the only interesting question for most people is “Is it the best tool to do X in terms of ROI or time to market?” and right now for many things the answer is still a “Yes”.
