Great name ... but I can't see why I would use howl.com if I already use facebook, twitter or tumblr. First, you need to work on what makes you distinct. Focus on the differentiation. If sharing links is going to be your core competitive difference, make is easy to use, make it mobile friendly. What would be interesting if is you could link duplicated urls that multiple users post into a single unique entry and tie all the comments together, or automatically dive down to the original source if the submitted link is on reddit or digg. Secondly, build your monetization engine into place early. I don't see how you'd make money, but I trust you have a plan. Build that into the mechanism before you get sidetracked by features. I'm a failed entrepreneur from the first .com bubble and I just got my MBA ... I wish I knew then what I know now ... Good luck! I hope all the best for you guys!
