sort companies by category ("food", "electronics",...)

When navigating the wikirate website, trying to find out what wikirate can do for me or what I can do for wikirate, I would have liked to have the possibility to browse the companies not only as an alphabetical list but by business categoy (fashion, electronics, food, cars, cosmetics etc.) to 

I'd be keen to put the electronics initiative in place of the little "quiz" box that cycles in place of the video on the homepage.

Re the categories, there's been a lot of talk about how best to handle that – most of it offsite for now, but I'll try to share more thoughts here on Wikirate.org from now on.

I think there's a pretty clear plan emerging to have "industry" be a metric (or metrics). So, for example, on "Volkswagen", an Industry metric would have the value of "Automobiles". There are actually lots of standards (national and international) for categorizing industries. If we take this approach, we can use multiple systems and the community can vote for the best ones. It's also cool to use metrics for this, because some companies change industry from year to year, and metrics are already set up to handle that.

So on the company page, the metric would show up in the normal metric list on the right (and possibly in some other sections, like "About"). If you go click to "view metric details", the industry metric would look mostly like a normal metric card, which would have a list of companies on the right ordered by their value (eg "Automobiles"). We'll also want to be able to filter by industry in several other places, like on the Browse Company page. Actually, pretty much anywhere a list of companies appears, we'll want to be able to pick an industry and filter by it.

I don't know if there's a timeline for this (could happen very soon if someone got really passionate about helping us get the data in shape!), but I don't think that's far off.
