Privacy Issues

I think it would be interesting to explore options to some of the "free" tools we're testing.  For example, this blogging service is extremely useful in enhancing our discussion and analysis, and a tool like Pownce, which allows you to easily share files with selected groups of "friends," could be useful in sharing information or when collaborating on projects/documents.  However, we should be aware of the user profiling these sites are doing and the sale of the data they collect.  Maybe I'm feeling like it's becoming more important to behave like a willing consumer than like a good citizen (or have they become the same?), but I'd feel a lot more comfortable using these tools if they were running on our own servers or if we could find alternatives (at a cost, no doubt) that wouldn't lurk over our discussions.  (Thanks to Ziba Zehdar for prompting this thought)
