I believe the main reason a person's postings on the Net can create problems is anonymity. So don't be anonymous. Use your real name, or don't post. Clearly identifying ourselves helps keep us honest - and undoubtedly helps decrease "the load of nonsense".
I try to practice this not only when I post, but when I judge a posting. If a name doesn't accompany a post, it has less credence. I want to know who is behind the words. I want to know they've put skin in their words.
Accountability is as important online as anywhere else. It fosters responsibility, and it fosters credibility. When you identify yourself, you also create a kind of bank account - with time, you build a solid reputation. You are who you are. When you try to be someone else, you start with a bank account of zero.
This is not to suggest that people who use screen names and post consistently good stuff aren't credible. And certainly some folks need anonymity online because of their corporate affiliations.
But I wonder - if we all were held accountable for our postings, would our words have more power to change the policies that prevent some people from speaking out under their own names? In a time when "intellectual property" is the real asset, why do people (and companies) want to suppress the identities of those who create that IP?
There will always be dopes who make themselves look bad online, whether they care or not, and whether they use a real name or not.
But the potential to build a solid reputation across the Net starts with accountability. Anyone who doesn't believe in the persistence of the image they create of themselves has a lot to learn - the hard way. Those who get it can prosper because the Net is a phenomenal amplifier of IP.
