The San Diego Space Society, of which I am currently serving on the board, will be hosting San Diego’s first ever unconference on space in early 2010. The whole point of an unconference is based on barcamps where the agenda is made the day of and everyone is expected to contribute and talk. So instead of someone talking to you for hours on end you are engaged in a conversation about space with other space enthusiasts and experts.
If you are interested in helping get the project off the ground (which I hope you are), you can contribute a few dollars and receive cool SpaceUp items like a patch or a t-shirt (or both). You can click on the widget to the left to help SDSS out or click here.
