A new study, reported by Mashable, finds that while nearly half of Americans use Facebook, only 7% use Twitter.  So, is it safe to ignore Twitter in marketing your law practice? The answer lies in an understanding of who uses Twitter.

According to the study, Twitter usage is dominated by “power users,” (approximately 22%) who are responsible for the majority of Tweets (approximately 90%). While these probably don’t reflect the target market of most lawyers, it’s logical to assume that this group of regular Tweeters is comprised of well-connected, avid communicators who could turn out to be a great source of referrals for lawyers.

I don’t think I’m going out on a limb here by suggesting that the frequent-tweeter club includes a lot of professionals, many of whom have followers in your target market. The numbers may be small but the influence is great. These are the folks you want to meet–and network with–and Twitter is a great way to find them.

Twitter is also continuing to grow and enter the mainstream. Those of us who have staked a small claim will benefit by that growth.

I don’t consider myself a power user of Twitter or any other social media tool. Far from it. But through Twitter, I’ve been able to meet some power users. And that’s the point. Networking is not about meeting everyone, it’s about meeting a few of the right people.
