Do you use Quora? Maybe you like learning or teaching or are just plain curious or are trying to get an answer to that question that Wikipedia or Google could not answer.
Quora is like Yahoo Answers on steriods. The answers come from real people (real names shown as opposed to screen names) and those real people are usually experts in their fields.
When time permits, I like to jump on Quora to learn about interesting stuff and sometimes even give my two cents. Here are some of my answers on Quora as related to real estate:
Real Estate Investment Question
Real Estate Redevelopment Question
Commercial Real Estate Lease v. Own Question
Commercial Real Estate Vacancy Question
