This article seems a bit stupid. Most of those are not lessons, but pieces of advice, and they're generally unsubstantiated. Some of them I would outright disagree with. For example: Have an office. This should not be someone's apartment. It should not be a bunch of couches, though a couch for naps is good. It can be a coffee shop, though that's far from ideal. It should have tables and good wifi -- and some whiteboards if possible. How is that a start-up lesson? Or even a valid piece of advice? Maybe the author(s) needs an office, but not everyone does. Other pieces of advice are borderline useless: Don't take too many shortcuts. Brute-force algorithms should be used judiciously. Encourage modularity when possible. Remember that ultimately components of your product might be worth money independently of the whole. If you need this specific piece of advice, you can't understand this description of it. All in all, this seems like a pot-pourri of oft-rehashed advice from blogs about starting up. Probably this "article" seems to bad because it is not actually an article, but a wiki page where people have added their pieces of advice. Not a great strategy for writing a good article.
