Why would you need to say you're using ActiveRecord or Ruby if you said you're using Rails? You've missed the point of the article.
Also, will everyone decide in 6 months times that, hmmm, you know what Ruby sucks and we should all start using BooRuubie next year instead?
Because I guarantee at the absolute minimum one of the technologies you mentioned will be out of favour this time next year.
Also, I can practically guarantee in a year's time when you come to do some maintenance work on that project and there's a bug and you google it, the code you find will be incompatible with what you've built.
Or someone new comes to setup the project and is googling about the config for something you mentioned, the article will be utterly wrong and will spend days just getting the damn thing to run.
