It seems that Kickstarter calls Open Source "Open Software".
How can I follow only these Open Software projects? I don't wish to invest in anything Closed Source.
You can track all new "Open Software" projects here:
There's no RSS option but you could can get the results emailed Daily or Weekly. Although if you want them Weekly I suggest using this list instead (since it shows all new projects over 7 days instead of 4 days in the browse list)
Hope that helps
You can now subscribe to an RSS feed of all the results
You can track open source projects by visiting the open source tag: http://www.kickstarter.com/discover/tags/open-source?ref=sidebar#p1
However, tracking via RSS does not work, at least not in Google Reader. There are RSS feed only for all projects or individual projects (see this link: http://www.kickstarter.com/help/faq/backer%20questions#ProfSett):
The notification settings in your account don't allow any specific tracking either:
You may be able to set up tracking changes with a software like Website Watcher. You can test in a 30-day trial if it works for you.
Apart from that, either wait & see or send a suggestion to the Kickstarter team.
