#1: XML DB has nothing to do with NoSQL. Even if there is some external similarity with document stores actually the main point of the author is that people don't want to perform conversions. This was not the reason NoSQL started at all and not our main problem with SQL in the latest years.<p>#2: This has nothing to do with Github or hosting of <i>source code</i>. Here the author was referring to sell the service of <i>running</i> a web application for you, like a forum or a wiki, and so forth. something like vanilla forums or wordpress.org are doing indeed. IMHO this prediction was more or less totally wrong, as the latest five years showed us that web applications are a big business but companies will try to rewrite from scratch the product they are offering in order to take it closed source, to offer more in terms of usability, and probably even for scalability concerns.<p>Actually the reverse happened, for instance Reddit instead to use a Digg clone wrote the code, and later released it as open source.
