After listening to over a months complaints about the loss of the LFG channel, and the resulting take over of the trade channel, Blizzard made the following announcement in the official forums today:

We're looking into several improvements for the next content patch however there is only one that we can talk about at this point in time as we wait on the go ahead for talking about any others.

The one we CAN talk about is a reimplementation of the Looking For Group channel. Unlike the previous incarnation that was global for everyone, this new channel will only allow those that are a part of the Looking For Group and Looking For More system to use it. This should boost not only the usage of the tool but allow people to discuss the types of groups they are forming and what they are looking for in a group or even in the event they want to take part in.

This is just one example of some feedback that we've taken into account and worked to implement in improving the tool. We'll share more as we can in the future.
