This post talks a lot about the chicken and egg problem, and the inventors of Reddit faced the same problem - no one will come to your homepage for the internet if it doesn't look like the homepage for the internet.

Do you know what they did? They didn't focus on one community - they faked it. Thousands of fake posts with fake comments. All scripted.

Then one day they started seeing posts they didn't write and it took off.

Reddit was built on lies and you can too :)
