When I see the excitement and 24/7 coverage of Quora lately, these song lyrics jump in my head:

There’s something happening here
What it is ain’t exactly clear

The rest of the song doesn’t really fit — but the buzz and sense of wonderment is ever present. From the people I talk to, nobody seems to know exactly why this is happening with Quora — a relatively young questions & answers site — but it’s growing fast and attracting great people.

Here is a good example by way of a tweet on how people are feeling about Quora 😉

No doubt, the site is solid, well built, and takes advantage of the facebook/twitter socialgraph in a very smart way. But Q&A sites have been around for a while, and most haven’t become a part of my day-to-day the way Quora has lately.

For me, the signal/noise ratio is incredibly high, and from it’s early days, it’s felt like a site for us internet industry people — lots of questions about startup life, funding, and valley specific stuff. I think a bunch of hand curation is going on to keep things very clean and smart. Here is a great recent example that I just wouldn’t expect to find on other q&a sites – and with people I know and respect answering the question: I run a SaaS company that just turned profitable…

But there are some mysteries too. For example, I hadn’t logged in for a few weeks, and when I did, I had over 150 followers — and was pretty sure I had close to 0 only a few weeks ago. How did these people find me ? I haven’t answered any questions yet — only voted up a few answers. Part of the answer might be because of this thread which alluded my google alerts for my own name: Who are the best business development people in Silicon Valley? (nice to just be mentioned among some of these rockstars).

The other mystery to me is that all these Quora pages are indexes in Google, but didn’t trigger a google alert — so maybe Google doesn’t see these responses to some of the questions. But where is the follower discovery happening ? Could it be just the facebook/address book import plus that sidebar ? Maybe ? Reminds me a bit of Instagram too — these social graphs grow very quickly now, without a ton of in-your-face promotion.

It’s going to be interesting to see how this develops. I don’t quite see a general q&a site taking off – in that it gets diluted like some of the previous q&a efforts, attracts lots of spam, and most importantly it’s hard to trust people from outside your industry — you just can’t be sure they are subject matter experts. It also feels like niche sites win over time — if I want travel/hotel advise I’m still checking out tripadvisor.com. If I’m researching a new gadget, I’m heading to gdgt.com . But maybe this time it will be different. I can’t wait to see how this turns out.
