The final installment of Technorati’s State of the Blogosphere survey from last week looked at the micro-blogging service Twitter. In particular, Technorati wanted to find out what use bloggers make of Twitter, and if they don’t use it, why not?

Remember – this is a global survey of bloggers, not the general public. It’s people who are at least vaguely familiar with Twitter.

As a result, not surprisingly, 73% of bloggers use Twitter and 27% don’t. But for the quarter who don’t it’s still interesting to see that what I’d call ‘Twitter myths’ lead the reasons for non-use.

For example, 54% said they didn’t feel the need to broadcast their lives (you don’t need to), 38% said the content wasn’t compelling (you pick and choose who you want to follow), while 35% said they just don’t get it.

Among those that do use it, only a quarter (26%) are blogging less, which shows that more often than not the use of Twitter and blogs go hand in hand. Indeed, 69% actively use Twitter to promote their blog. This ties into a theme of previous posts, that Twitter is essentially a bridge to other media.

People listen to what’s said and if something breaks, they take it elsewhere.
