I haven't joined the world of Instagram personally yet but I know that more and more firms are there, and as a fast growing channel, it has the potential to reach decision makers in a different way.  This piece talks about who is using it well for B2B, and King & Wood Mallesons have been highlighted elsewhere as a good example of a law firm who've joined the fray. 

So is it all about portraying your firm's culture to build on recruitment comms, or more about engaging with clients and showing them what your people get up to?  I'm not sure what's best yet, but I'm certainly going to be taking a keen interest from now on.
