It’s always interesting to watch how systems set up by a platform (hashtags on Twitter in this case) are taken up by the communities using it and evolve with their requirements [Mags makes a useful correction below in the comments to point out that in fact the Twitter community introduced hashtags and Twitter later picked up on it, thanks Mags]. Hashtags were, I imagine, set up with a view to organising conversions so that people could join groups discussing certain topics. For SEO this means getting your message heard or just lifting your profile is easier when using hashtags to join conversational groups and meet new people.
But hashtags are used in all kinds of other ways, (like many others we even use ours as a trigger for our website to pull in a Tweet to the homepage) and I’ve noticed a growing trend in my fellow Tweeps of using a hashtag more as a short snappy full-stop to a message, rather than a tag they actually expect others to be using or to take on.
So, I’m interested, when you use hashtags in your Tweets, what is your intention? Do you give it conscious thought, are you trying to join other conversations, are you doing it just for fun?
