Good luck reading that title. I'll bet you spent 5 minutes just trying to figure that out.
By now, most of you have an instagram, twitter, vine, or some other social media platform that use hashtags. However, each one of these is unique in the way that you are expected to use the hashtag.
Instagram - A fun and easy social media site. Apparently there is an unspoken rule that girls are to use a minimum of 3 hashtags per picture. And if its someones birthday, you are required to use no less than 10. Food, at least 5 are needed to get your point across that you are enjoying the food. But the point is, there is not a goal for creativity, originality, or awesomeness in a hashtag. As many as you need.
Twitter - this is the last great social media frontier. A friend of mine said "brevity is a sign of wit." Another friend said "twitter is cool." Both true statements. Twitter only allows 140 characters for expression. So you have to be brief. Meaning, your hashtags must be witty, funny, clever, or non-existent. Not using a hashtag is also a sign of intelligence in this hashtag-saturated world. Twitter? 2 hashtags MAX! There is no reason to go on and on with hashtags. Why? Because you can't. You don't have room; and because twitter is the place for the clever and the brief to express themselves. Moral of the story, one hashtag should be plenty. On a rare circumstance you can include a second, but only if both are epic.
Facebook - hashtags don't work. Stop putting them there.
Vine - don't have one. But from what I can tell, see instagram advice above.
Oh and one more thing, just like my title, hashtags that are too long are obnoxious. Try using CamelCase. #ThenPeopleCanUnderstandWhatYouHashtagIsActuallySaying
