Google’s latest initiative, just launched officially September 23rd, is something anyone with a website needs to pay attention to.
Sidewiki allows anyone with a Google account and a Google toolbar to comment on any web page – and have it be visible to others.
It can also show up in searches.
Multiply the negative potential of Wikipedia by 100x, and you picture the concern.
Of course all may turn out well. But I wouldn’t count on it. After all, it enables your competitors to make negative comments anyone can see about you!
It’s experimental and I think there’s a fair chance it won’t pan out because there’s no good way to control abuse. The mechanisms which mainly keep Wikipedia from going too far off the rails, won’t work with this set up.
Definitely you should be checking regularly to see if anyone is posting entries for your website.
