How do hashtags on Instagram compare to hashtags on other social networks?

<p>I would like to know what people think about how hashtags on Instagram differ or compare to hashtags on other social networks like Twitter. Do the applications of hashtags - advertisement, organizing and categorizing ideas/themes, finding users with similar interests, promotion of an artists/company, etc. - benefit Instagram users significantly more than users on other social networks. How do they compare? And what are the benefit of either?</p>
