List of my Social Networking Tools?

I recently received a request from my boss and our IT dept for a list of "social networking tools and other technologies" I'm currently using or investigating. I have no idea what they will use this list for except for the vague mention of "proactively assessing" these tools, I assume for security purposes. Hopefully this won't lead to a culture of restrictions and red tape. To me, that would all but kill the lifeblood of a major part of my job and our library: innovating and experimenting with new and emerging technologies to improve library services.

Anyways, a got a couple requests for the list, so here it is...

Note: I'm not clear on how they're defining "social networking tools", so I've included below (which is basically what I sent to my boss) just about anything that has any sort of social/networking component that I use in any work or professional development way, or have bookmarked for future assessment in those areas:
