Yeah but it isn’t a sewer though — it’s a junk shop or an antique store or thrift store. I get a lot of very helpful information for my work from Twitter. I’ve become dependent on it as a news net or a bulletin board of sorts. Unlike with straight news sources, where I simply choose not to read editorials very often, it’s harder not to do that given how Twitter pushes tweets to the timeline. Its also immediate and bullet-pointy which is both a charm and a limitation. How the pushes work is something LinkedIn and Facebook are much more careful about, and no one that matters to me uses Facebook for work. So I have a vested interest in ensuring Twitter remains as “clean” as possible, which is harder to manage the way it works. However, this will force one to clean up who/what you follow I guess.
