Alas, this post is a lament.
Way back when, there used to be a website called Askme.com. A friend of mine introduced me to Askme, which filled a niche similar to Yahoo! Answers today. Unlike Answers, people needed to specifically register to answer questions in a particular category, and in doing so indicate how they were expert in the topic. Users of the site rated answers in the standard manner, and experts were ranked both overall and in their categories of expertice.
The Askme community is probably the most vibrant of all of the online communities that I have been involved with over the years. In every category in which I was active, there were users who I truly got to know – both experts and people asking questions. People stuck around for years, and got involved in maintaining their categories.
Unfortunately the company decided that running a free website to showcase their technology was too expensive, so they shut it down in order to focus on selling their software to Fortune 500 companies instead. The hundreds of thousands of committed experts floated away along the internet’s pipes, and so far I have yet to find another site that I truly felt at home participating in to the same extent. From what I’ve heard, I’m not the only one.
