What about having tags?
I think it would be cool to tag posts, to make finding posts you need easier.
Yeah but tags are usually used when searching for topics and based on how many "OMG WE SOOOO NEED NEW LANGUAGES :DDD" posts there are, it seems that the search function isn't being utilized to its full potential.
First the search bar should be moved and clearly visible. Maybe more centered towards the top of the page.
Then tags would be a great idea, especially when searching for your own posts.
