Foos is here!

We really should have done this awhile ago, but we heard from enough of you that you wanted to be able to subscribe to a feed of the Daily Angle that we decided to build the feature last week. Over time, we’ll add more things you can subscribe via RSS for all you feed demons - send us feedback if you have any particular requests.

When you contribute to an article, you develop a sense of attachment to the article. It’s not that surprising - you helped make it better, and so you want to watch it grow and see who else is editing the article too. So we’re launching a feature that helps you do that - the Article Tracklist.

We think the Tracklist will help you keep track of what’s changing to the articles you care most about. How does it work? It’s pretty simple, when you edit an article, we’ll give you an option to track changes to the article. If you decide to track changes, we’ll add it to your tracklist, and then we’ll email you when the article changes (unless you opt out). If you ever want to stop tracking an article, you can do that on the article page itself, or manage it on your tracklist settings page.

It’s that sense of passion and ownership that we think helped Wikipedia’s contributor base grow to be as good and as broad as it is, so we’re hoping the Tracklist will help you too. As with all new features we launch, please send us feedback!

We’ve got one more new project that we just added to the How To Contribute page - annotate a WikiChart. As for suggestions on what to annotate, we built some logic to help detect the most significant changes in a stock’s price in the past week. Go check it out, even just browsing the big jumps. For you value investors out there, this could be a way to discover some stocks that have been recently hammered - and for you growth investors, maybe you’ll find some interesting momentum rides (and hopefully the WikiChart annotations will help you figure out what’s actually going on!)

Ever wanted to get involved, but not sure where to start? Well Anton’s been hard at work building a cool new How To Contribute page that we’re launching today. Right now, there are three projects highlighted: Start an article, Fix some grammar, and Define a term. For each project, we’ve tried to suggest some of the most useful places where Wikinvest could be improved or expanded upon, so if you’re looking for somewhere to get involved that will have a big impact, go check it out. We plan on adding more projects over time, so send us your ideas for what else we should include on this page! Over time, we see the page evolving to become a Contributor Central of sorts.

In case you’re curious, we’ve gotten a bunch of coverage surrounding our official launch. Check us out in Wired, TechCrunch, Mashable, Podtech, VentureBeat - keep them coming!
