VGChartz was the right concept. Gather the data and post them on your own website which is the money generator.
Things were going very well and the accuracy was increasing year over year from 2007-2010 and then I don't know what happened and everything fell apart. Either ioi was trying too many things with the website back then, data base, Pro site, another website, paid writers and other things, and it backfired or he got too busy with other work.
If someone can replicate that concept and improve on the accuracy it would be great and could help you get investors. You can get people like ioi to advise you on how to gather data, what worked and what didn't and what were the things that prevent him from being a credible source of data. You can promise people like him advisory shares.
