I thought about creating one of these a while ago but there's a lot of other people building them right now and I don't think any of them are really doing that well business-wise. I like this particular on covered here the best so far actually - its easy to select options and narrow down on a search. I think theme sorters/finders solve a real need after spending an endless amount of time browsing the fragmented theme market. Having said that none of the current sorters make it that that attractive to use them if all they do is aggregate and sort. I think that's why some feel hesitant to click on affiliate links from one of these sites.

I think these kind of sites can provide a more tangible experience by addressing some of the other needs people have when looking for a right theme. For example, I often have to hunt for a theme for a client, a friend or myself. I'd love to be able to save themes I liked in a list that I can share and comment on.

Another perk for consultants/designers looking to recommend a theme would be to get an affiliate sale without having to register for all the different theme shops and using a theme sorter service as the middleman.

It would also be interesting to have a weekly updated Theme Chart with the best themes like they do for music charts. Designers might find it fun to see their theme topping a chart, increasing the competitive fire (which I think is a good thing).

Those were some of the features I was thinking about at least...hope someone picks 'm up.
