The @stackmma twitter bot tweets certain questions (algorithmically determined) and converts the first tag (sorted by number of questions) to a hash tag. Hash tags are twitter's way of sorting things and the article says:
- People use the hashtag symbol # before a relevant keyword or phrase (no spaces) in their Tweet to categorize those Tweets and help them show more easily in Twitter Search.
- Clicking on a hashtagged word in any message shows you all other Tweets marked with that keyword
- Hashtagged words that become very popular are often Trending Topics
Now consider this question that was tweeted to an obscure hashtag #customnotation... In reality, nobody tweets/looks at such obscure #tags. In other words, our classification scheme is not a good fit for what twitter users use. In comparison, the #mathematica tag shows more activity, and I believe, could become moderately trending tags during the release of version 9 or the conference (unless some celebrity has a wardrobe malfunction yet again).
Now we can't use mathematica on our questions to enforce this as it is a blacklisted tag on this site (because it makes no sense to tag something mathematica on a site called mathematica.SE), but I propose that the twitter bot ignore any site tag and instead tweet all questions to #mathematica. This would possibly reach a more relevant audience and possibly attract more followers.
