The Future of Social Networking?
Michael Arrington, founder of
TechCrunch, offers some valuable insight into mobile social networking
in a piece at Seeking Alpha, an investment site. The article keys in
on
what is required for effective mobile social networking. For starters
it "requires a social network that has presence, location and
contextual information about you. It needs to know where you are (via
GPS or triangulation), if you are in business or personal mode, and
similar information for the people around you." Arrington claims to
have seen the future in a new startup, details of which he can't
disclose, and feels we are on the verge of the next big app.

Purdue University's Project Vulcan
studies and maps carbon dioxide (a key "greenhouse gas") at a much
finer scale and with greater frequency than has been achieved by
previous studies. According to the site, "We have built the entire
inventory on a common 10 km grid to facilitate atmospheric modeling.
Vulcan is available at the hourly timescale for the year 2002. In
addition to improvement in space and time resolution, Vulcan is
quantified at the level of fuel type, economic sub-sector, and
county/state identification." The map below shows a sample of the 10
km
data. Copyright Purdue University, used with permission. Click for
