Wikispaces and SourceForge, Now Even Better Together. This is pretty big news for Wikispaces – and for wikis in general. It’s also great to see a company that’s been so supportive of education also being supportive of open source software. In short, “Wikispaces and SourceForge have teamed up to provide wikis to the 1.5 million open source software developers on SourceForge.net.”
