I don't think I can define intimacy. Maybe I could say pretty definitively that intimacy doesn't just have to do with couples, with lovers. Intimacy isn't just about two people in love, being physically and emotionally close. Intimacy changes (can be queered) depending on the space you're in, with whom you're being intimate (in whatever way), and what that feels like. Intimacy is about kin, family (chosen and not), friends, and connections.
Tracking intimacy definitely gave me a wider range of understanding what its definition could be/is. It also made me less certain of one single meaning for the word. I don't think that I came up with a consensus throughout the semester on what intimacy is. But I think that that's okay. I'm okay ending with questions.
I would say, on the whole, the blog entries and the availability of twitter were helpful throughout the semester. I think I engaged with other peoples' thoughts in a way I wouldn't have if we only had in-class discussions. I explored the limits of the blog more than I did twitter. But I think the diablog was the best synthesis of blog, twitter, and in-person discussion that we had throughout the semester. When I had to facilitate the diablog discussion, I was on twitter like a crazy person, and really used the blog posts I wrote to work through the readings. And having people discuss what I'd written made the work that I'd done have a purpose/be worthwhile, and it helped me to work through my thoughts even further. If I were to change anything about my participation, I would be a more active tweeter. And I would make it so one could tag one's comments (because it's so annoying to not be able to see my comments listed under my tag).
I think you, @undisciplined, should definitely keep the same format for the first couple of weeks--lots of tutorials, not too many blog posts. It really helped to get me acquainted with the blog. Other than that, I think I would have liked different twitter assignments, maybe an experiment with live tweeting in class? But that's just me, and I'm still intrigued by twitter and its possibilities, especially as a way to have a conversation and critical discussion online, while also complementing/diverging/differing/supplementing an in-person discussion.
