I'd like a little button on Twitter that would allow me to designate up to a dozen of my tweets to serve as an introduction to my main concerns, producing something like this: What's @KenSmith about? It's about these dozen tweets, the issues they raise, the small points they begin to make, the fuller resources they point to elsewhere.*

As it is, Twitter sort of relentlessly says, "You will not shape anything but the endless, ever-vanishing flow of tweets in our space. On our terms, not yours. With our goals in mind, not yours."

*A grander version would allow a writer to link old and new tweets in a chain at any time--not just one of these, but any number of theme groups of tweets or tweets that add up to a story.
