Agreed, early Quora was interesting, it had a buzz and you got answers from people you wouldn't expect.

Now, it's spammy. Some of the questions are ridiculous, with easily Googleable answers, but makes sense if it's spammers using Q&As to raise profiles of people and services.

Quora now also appears desperate. I occasionally answered questions but doing so would trigger something like three emails a day asking me to answer another question. That level of desperation is offputting, so I just unsubscribed and as a result don't answer any more.
