I don't think it's either of those things - biologists and biochemists just seem to be ridiculously busy, in part because of spending to long in the lab trying to get your crap to work. Every lab I've been in has an inefficient process by which people share, modify and troubleshoot their protocols amongst themselves - but that's convenient because you can ask the guy on the bench next to you. How to get researchers to invest more time and effort, communicating with people they don't explicitly have to, is the problem.
