Being an excellent communicator is a great virtue to have and something I come to value more and more in co-workers. Once upon a time in my career it was standard for devs to wander off into the woods to painstakingly craft a wonder over 3-4 months, now collaborative working is the thing and it's far more productive. Those people who have the right balance of not being constantly dependent on others but knowing when they need to tap someone in and, specifically, knowing how to get someone up to speed quickly for that tap in - those people shine brightly.

Being a good communicator is probably what I'd ask new devs to focus on the most - it's going to pay out a lot more than an encyclopedic knowledge of algorithms or creative problem solving and it's the only skill that everyone on the team greatly benefits from.
