this article holds especially true for non-technical entrepreneurs deciding which language to choose. while the supply of developers may be lower for languages such as ruby or python, you find a much more enthusiastic crowd of developers who in general seem to already have graduated from another language such as php. thus, from a business non-technical background, by choosing an enthusiast type language such as ruby it made it easier to narrow down quality developers with the right mentality as a technical co-founder than say a language with a large supply of developers such as php.
