Today, Mashable posted this fascinating chart comparing 2010’s top Twitter trending topics and the trending topics that were most popular in 2009. Clearly, the zeitgeist has changed at least a little bit, but what’s really interesting is what this says about how Twitter usage has evolved — especially the significant increase in hashtags.
Are users simply getting more savvy about how Twitter works, or do you think the change can be credited to the various interface changes Twitter has made over the past year? Personally, I think it’s a combination of both, with a sprinkling of the fact that as businesses, brands and personalities become more Twitter savvy, they’ve upped their hashtag usage in contests and content as well.
Plus, I have a sneaking suspicion (no hard data, just anecdotal and directional observations) that hashtagging your tweets makes them more valuable for SEO. And I know I’m not the only one who thinks that’s the case.
All told, it looks like 2010 could be termed the year of the hashtag…or, in other words, #Hashtag2010.
