So this is an interesting bit of news.... AndrewFoundry says that there was a bug on the old site that distorted the love percentage that photosets received. Sean and the development team had to make a tough decision not to replicate it in the new site, and as such percentages on the new site are quite different. Coupled with the fact that comment counts will also be lower since clicking 'I loved it' won't count as a comment, and the fact that you can only click 'I loved it' or 'Not for me' once, and the whole numbers game changes.

All in all, probably a good thing, but I imagine some people might be disappointed by the change in numbers!
