> I have some 1500+ articles multiple of which are 50+ pages

Holy shit. Make it public.

The idea is fantastic. I would love to have something like wikipedia but people have separate pages on topic.

Or, in other words, if you want to find everything written by given person, why not that easy it is doable - it was more doable back when blogs were more popular.

But if you want to find everything on given topic written by different people that's not such an easy task. I feel like it should be solved soon by machine learning and evolution of search engines, but you still have the problem of which authors (or inevitably bots) do you actually want to see. This can be solved with a global web of trust.
