I am a professor running a research lab. I use Botnik to keep my team connected and engaged. Even though I'm all over campus and constantly busy, I can stop in to the Botnik website and see what's up with everyone - what they need, whether they need support, etc. Grad school is hard and knowing my advisees and team members is helpful. It also helps them to understand each other's struggles and triumphs.
I haven't started using the insight questions, but I bet that getting my team's ideas about our research that way could be awesome.
