I don't even know where to start.
In terms of new features, there's a laundry list. We started with adding auto-tagging: every post automatically has keywords extracted from it and added to the post's tags. This makes finding new content *so much* easier, because two people may label an article about baseball in two different ways: "I love baseball" or "I love playing America's national pastime"-- but they both will inevitably use the word 'baseball' within the text. This would then be a tag applied to both entries, and a search for 'baseball' will return both relevant links, without having to resort to a full text scan. Yes, we do this tagging automatically, and no I won't tell you how. If you're interested, send us a resume.
What good is auto-tagging if there's no good way to show the tags we derive? Right! As a complementary feature, we introduced a snazzy new tag cloud that's always available. Wherever you go on the site, just click the big green "Explore" button hanging off the top menu, and you'll drop down a fresh list of tags that you can peruse to see what catches your fancy. I'm more of a hockey fan, myself... Oh, and you check out the Zeitgeist of our tagging world by going to the tags home.
We also added autocomplete functionality, so when you're typing in the main Experience box, the site will try to show you similar items. Maybe someone else already entered the experience, and so you can join the group rather than being a pioneer.
Sometimes in life, you don't like someone and you'd prefer not to interact with them. The same thing can happen at the Experience Project. So we added the ability to block users. Just browse over to a certain offensive someone's profile and hit 'block member.' You know what happens next.
There's tons more things that are fresh (we make the site better EVERY day, no exaggeration), but I'll only talk about one more because it's so useful. Now you can subscribe (or watch, whatever language you prefer), experience groups. Meaning that if you like a certain group, you can go ahead and tell the site to email you whenever there is a new story. We want to make sure you don't miss a story, and likewise make that process as convenient for you as possible.
OK, that's a quick rundown on the changes for the last few weeks. Hope you enjoy them, and as always, let us know what you think. We really like you, and we're going to try our hardest to make sure you feel the same about us. There will be another post like this in about a week's time. Watch out now.
