There are loads of legal blogs and rags out there which cost nothing to subscribe to, and even more in the legal publications space for a small fee. We've seen on this site alone that vendors are watching and are happy to plug their wares so there's simply no excuse for not being informed. And in any selection of software or services, particularly in a law firm where you're likely to get next to no recognition for a good decision and typicallly crucified for a bad one you'd be mad not to take a little extra time to do your homework.
