Blogging has become a critical piece of my business. I am an early-stage investor in Internet-delivered services and the co-founder of a venture firm. At first I really didn't know what to write about. So I wrote about things I was passionate about: work, family, music, politics, New York City. I still post about all of those things, but today my blog, called A VC, is mostly about my work and music. I started writing at least one post every day and have done that ever since. When I go on vacation, I write a bunch of posts in advance and then autopost them on a regular schedule. I've found that having something new on the blog every day is the single most important thing to building an audience.

I also like to use a sensational headline. Many people read blogs in aggregators, which generally show only the headline. So you have to give people a reason to click through. Blogs need to be real and personal. Reading it should be like hanging out with you. I play music for my readers. I show them videos I like. I tell them what I did over the weekend. And I tell them what is happening in the technology, Internet, and VC markets.

And it works. About 50,000 people come to my blog every month. The site brings in about $30,000 a year now in ad revenue, and I donate it all to charity. Most important, I'm getting to know entrepreneurs of all kinds - in India, Australia, England, China, and Silicon Valley. They read my blog, correct me when I'm wrong, pound the table when they agree with me. I get to know them, and they get to know me. When it comes time for them to raise money, they know who to ask. And for me, the blog acts as an amplifier and a filter. I see many more opportunities, but they are also way more relevant. It makes me a better investor.
