To those who lost big on the last Dot-Com bust, I suggest you sell short on any Blog software stocks. I read an article just yesterday about some company that sells blog authoring software--the article gushed about how 'hot' the stock is.
My honest guess is that the company won't exist (at least not in their current business model) in six months. I pity those who'll make the same mistake again so soon after the recent bust and put all (or any of) their money into such a company, unless you're day-trading or playing the short hops.
