Certainly the explosion of Instagram plays into that and Facebook's introduction of hashtags back in June has the FB crowd suddenly all atwitter with the topic (more on that further down).
And even though we can't find official confirmation on Instagram itself, Hashtag.org reported the other day the popular image-sharing network has banned a rather long list of hashtags for being porn-related or curse words or too explicit or downright offensive.
The list is reported to include even, "#Instagram, which when one thinks about it is kinda dumb to hashtag Instagram on Instagram. (This ban is said to be too general, along with #iPhone, #photograph, #popular and others, so as to confuse searches.)
A blog by Australian entrepreneur Nick Drewe called, "The Data Pack," seems to have started the notion of the banned hashtags by publishing a list of phrases one should avoid. You can read the list for yourself. One has to admit, most are just plain nasty.
On the other hand, web.stagram.com/hot has published a list of the Top 100 hashtags used on Instagram. Rounding out the Top 10 are: 1. #love; 2. #instagood; 3. #me; 4. #cute; 5. #follow; 6. #photooftheday; 7. #like; 8. #followme; 9. #girl; 10. #tbt.
Hashtags on Facebook? Meh, not so much.
Although not even in use three months, yet, the first study of hashtag use on Facebook doesn't look so promising.
"(EdgeRank Checker) looked at more than 500 pages in July. These pages had a combined total of 35,000 posts and at least 6,000 of those posts contained hashtags," reported Search Engine Journal.
"Results show that hashtags on Facebook resulted in less viral reach. There was a measurable decrease in the amount of engagement per fan which was consistent across all pages regardless of the total number of fans a page has," explains the report.
The study also, then, other the alternative use on Twitter.
"By comparison, EdgeRank Checker also analyzed the Twitter accounts of 50 companies listed in Fortune 500 to find that using a hashtag typically resulted in twice the likelihood of being retweeted," it was reported. "More than 70% of the accounts analyzed had an increase in retweets when using a hashtag compared to those that didn’t use one."
