Renal physiology and pathophysiology is widely regarded as one of the most challenging subjects in the pre-clinical studies of medical school. The challenging subject has been blamed for the downturn in interest in our fine specialty. To help combat this we have started an initiative where a medical students can post a question to Twitter and get an answers from practicing nephrologists and basic scientists. See the kick off post at PBFluids.
The way this works is, if a student has a question they post it to Twitter with the hashtag #AskRenal. We have a bot that scours Twitter for this hashtag and will retweet the question while tagging @NephJC. NephJC will amplify the question to its audience of nephrology nerds who will then provide answers tagging the initial questioner.
