I have envied working under great managers and to work in teams where there is a lot of learning. This tool can help people find jobs that is not available elsewhere, because the job has not been vacant yet. Also, you can get a first hand account of the role from the person who is currently in the job position, if you are a match.
Full disclosure: Me and Bouchen met in StartupSchool forums and I liked this idea and helped him build this product.
If you want to move things fast - you can spawn off a new social news site in slinkset.com and you get a basic social voting site similar to http://help.slinkset.com
But if your intention is to learn how such a site work, I would recommend you to write one from scratch, and there are many open source reddit clones floating around, that can help you
Why not create a mail with a 250 character limit. Or forget the limits, something like the facebook stream, but a lot more private just like email. Not sure if such a service exists today..something like a Short Message Service implemented with email protocols.
Pretty decent. Have been using it for the past 3 years
