As a mod on the Academia site, I want to emphasize that we're not trying to be "mean" or "exclusive" or anything. The Academia site is geared towards researchers and those doing research. It just so happens that most academic research takes place in the same buildings where undergraduates go to college. However, these two "fields", as you were—undergraduate studies and academic research—are actually very distant. Academic research questions will likely focus on education- and career–related topics, such as:
- career advice
- dealing with coursework & working
- tuition
- teaching questions
- TA questions
- software related to studying
Whereas questions on Academia are much more geared towards research, focusing on topic such as:
- grant agencies
- dealing with publishers
- setting up with and maintaining collaborations
- cooperating with advisors
- motivating undergraduates
- academic career paths
- academic administrative duties
The only similarity between the two is the university setting, but that's really about it. The community has voted in the past against including undergraduate questions, and considering the above I tend to agree.
