This discussion does seem to get a little exhausted over time. All in all I think most of us come to the same conclusion:
- best case scenario is to write your own content. This way you guarantee uniqueness, relevance, great client assistance and even some food for SEO. I doubt anyone would want to skip that.
- smaller hosts (which as far as I remember EasyHostMedia once mentioned they were, sorry if I'm mistaken) might want to resort to buying a premade KB and build up on it as writing it themselves would prove to take a LOT of time and effort. A simple example - when we started our WHF KB, 2 people were doing nothing but compiling information and writing articles all day for a week. Now imagine if your whole staff is 5 people and you have to take care of servers, customers, development etc. in the meantime.
At the end of the day there is no right and wrong here, just an optimal usage of the available resources.
