I just read abouton .
It's a conference aggregator for lack of a better phrase. You'll see two lists of conferences in the panel to the right. The top list includes conferences that will be happening in the next month (in red), conferences that have already happened in the last month (gray), and any conferences that are currently going on (blue). The longer list beneath includes all of the conferences that have been registered on hitchhikr. They are sorted by popularity.
Totally awesome! I have added a couple of conferences already – and I’m planning on keeping an eye on this site for other conferences I may be interested in.
