The promoted tweet is a real tweet that a company may have sent out that they want more distribution for. They will buy key words for it. If people are looking for something related, it will show up.

I was broke for more than 10 years. I remember staying up all night one night at my first company and looking in couch cushions the next morning for some change to buy coffee.

The key really is distribution.

People want to do good things, they just need a prod sometimes, and what Twitter and other technologies that connect people are showing us is that if you make it a little easier for people then you will enable them to do what they want to do, to help people out, to form groups and do good.

My strong belief - in being in blogging before Twitter - is that in trying to create more information out there, in trying to create the democratization of media in general, is that the more voices there are out there then the likelihood is that the truth bubbles up to the top.

A key element of Web blogs is the community element. Most blogs are not self-contained; they are highly dependent on linking to each other.
