Are hashtags useful?
from 10,000 Words
From a journalistic standpoint, the hashtag isn't only an eyesore, it's remarkably lazy. The problem with hashtags lies in their relative ambiguity: There's no standard for hashtags and no long-running conversation. For example, an event like SXSW can have relevant commentary with any number of hashtags, including #SXSW, #SXSW2013, #SXSW13, #SXSWi and much more. Hashtags are even worse when the goal is engagement with readers, since it's rare that you'll get a guaranteed audience for any of it.
