HowFlow is the place for finding tips and tricks for all sorts of Ruby on Rails/Ubuntu/Debian/programming geekery. If you’re a little rusty on your linux skills, HowFlow maybe useful to you. It’s a Berlin based site that was created with the Digg community voting and popularity style in mind. Users can submit their own tips, tricks, websites, and howtos or simply check out the front page to see what’s popular. The ranking systems allows the most popular articles to make front page, while the rest get upcoming page status. You can search for topics through the tag cloud, categories or search bar and feel free to join and paste your own comments. The site is currently in beta, so it’s a bit sparse on the content side, but looks promising once there’s more.
