When I meet with the founders of a new company, my advice is almost always, 'Do fewer things.' It's true of partnerships, marketing opportunities, anything that's taking up your time. The vast majority of things are distractions, and very few really matter to your success.

Every major communication tool on the Internet has spam and abuse problems. All email services, blogging services and social networks have to dedicate a significant amount of resources and time to fighting abuse and protecting their users.

If you look at the Internet, the vast majority of start-ups are not successful. But the ones that are, are very very successful. So you can't point to the unsuccessful ones and say, 'There's no hope for this field.' It's just that they had the wrong idea or they had bad execution.
