Perhaps inspired by bloggers' frustation with AdSense, TypePad has introduced a "tip jar" which offers bloggers "the opportunity to enjoy the fruits of your effort" by giving visitors ways to contribute using PayPal or a credit card. Give TypePad credit for introducing a new concept in a competitive market but I'm not sure the idea - although intriguing in concept - will work because a visitor has do something before a transaction can happen. This is why AdSense doesn't work for many bloggers because the people visiting are mostly there for a quick read even if a contextual ad is conveniently nearby. Despite some reservations, Michael Parekh is putting a tip jar on his blog "not for the money but the experiment of what people do when these types of features are introduced" - and he plans to donate the proceeds and those from TypePad's contextual ads to the Red Cross. Fred Wilson figures his "tips" are comments, links and e-mails . As for AdSense, it took me six months to make a whopping US$130. Then again, if I wanted to do something for money I'd be begging for freelance.
