I feel like when I load up the "your thoughts" page, my streams should be placed more prominently, instead of general thoughts. Again, I think the focus should be more on the thought streams than the general thoughts, which make it stand out from twitter.
And since I'm talking about twitter, I like how twitter only has a single line text box that doesn't take up much space, which expands into a bigger text entry box once you click on it. Maybe that's a detail thoughtstreams could adapt in the future.
