Judith Middleton (partner at Latimer Hinks Solcitors), Anne Elliott (partner) and myself write blogs. All are very different.
Social Networking Guineapig follows the success of Judith's Divorce Blog and Anne's Tax Planning Blog as well as providing the opportunity to flag up events, press stories which Latimer Hinks publish.
We are a 9 partner firm and so far I have only managed to recruit 2 partners in this blogging experiment.
Here is my blog on Why Blog - the advantages
The reasons that Latimer Hinks have developed blogs as an added marketing initiative are given below in a quote from KMSpace (we seem to be on the same wavelength!)
Blogging, like any marketing or networking activity is about building your brand. With lawyers and other professionals that means showing your expertise, engaging in conversations about your expertise and publishing your expertise. Blogs allow all of these. And certainly do a better job than most firm's rather static websites.
Once you start a blog it's interesting (and addictive) to monitor how much traffic is directed to the firm's website. Traffic that would not have arrived there probably by any other means.
All you need to do is "give it a try". It's free and your marketing budget will stretch further!
