Although Twitter's initial response to Messina's proposed use of hashtags was negative "these things are for nerds" a series of events, including the devastating fire in San Diego County later that year, saw the first widespread use of #sandiegofire to allow users to easily track updates about the fire. The use of hashtags itself then eventually spread like wild-fire on Twitter, and by the end of the decade could be seen in most social media platforms including Instagram, Facebook, Reddit, and YouTube, so much so that Instagram had to officially place a "30 hashtags" limit on its posts to prevent people from abusing the use of hashtags.
