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!

We’ve gotten lots of mail in our feedback inbox from people who have ideas for how to improve articles or are just telling us they really like an article. But the irony is although we love hearing from you, we’re not the best people to send this kind of feedback - the best people to tell are the authors of the article themselves.

The authors are the ones who deserve your praise and can make the best use of the feedback you have. So we’ve built a little feature that helps make it easier to do that - the suggestion/comment box. Tell them what you think about the article, give them ideas for new things to write about or ways to improve, or just send them a note thanking them!

We’ve spiffed up our home page - check it out and let us know what you think!

Ever wanted to see who’s helping to create Wikinvest? Well, we’ve built a new Contributors page to showcase you, our community! All you contributors out there who haven’t uploaded a picture or filled out your contributor profile page, now there’s another good reason.

We had a little team go-karting outing this afternoon and Roger took the checkered flag. That guy is fast. Jason got crap from us for positioning himself for winning “most improved” next time Can somebody tell us what we should do with all our head socks now?

So we’ve gotten a bunch of people asking how to pronounce Wikinvest.  We know people will probably continue to pronounce it differently or misspell it, but for all of you who are curious, it’s Wick-in-vest.

In celebration of Anton’s twentysomething-eth birthday we baked a fabulous three layer cake: angel food with fresh strawberries and marscapone frosting. There weren’t enough cake pans for all the layers so two of them were baked in skillets. The odd bun-like shapes that resulted didn’t turn out to be the best things to work with (the cake resembled a Big Mac that was drooling cream), but it was delicious.

The take away message: work at Wikinvest and get a tasty burger-cake on your birthday.
