I am willing to build a wiki-based website that would have some other features, namely comments, social sharing, video insertion, article rating and gamification. In a nutshell, something very close to the StackExchange's websites, but the pages would consist of a single piece article instead of a thread of questions implementing the footnote feature.
I have not coded a single line yet.
I am rather experienced with Grails, so I know Groovy and Java. I also know JQuery and a bit of PHP, but I can learn basically everything required. I will be the only one programming on the project.
My questions are:
Which technology should I use according to YOU ? Should I use Grails as this is what I know best, and try to integrate a wiki technology within my app (if yes, which one) ?
Should I start from an already existing wiki technology (WikiMedia, XWiki, TWiki, Moinmoin, ...) and modify it to integrate the features I need (gamification, comments, video insertion, article rating and social sharing) ? Once again, if you think that is the best solution, please quote a technology, and if possible, tell me why is this THE one.
Thank you very much for your help. I find it rather hard to choose, and ever harder to know which path is the right one to go. Any suggestion is most welcome.
I would suggest using MediaWiki for the following reasons
