This is going to be big.

Charlie at This Is Going To Be Big has some pretty useful ideas about building great companies, like these 10 Steps to a Hugely Successful Web 2.0 Company:

1. Solve the smallest possible problem (that is still big enough to matter) for the user and know exactly what problem you're trying to solve.
2. Get a responsive and chatty audience using the product.
3. Launch. Now. Tomorrow. Every day.
4. Distribute. Distribute. Distribute.
5. Don't hold users against their will.
6. Be mindnumbingly simple.
7. Get people hooked on free.
8. Don't waste any money on marketing.
9. Don't overfund.
10. No one sucks.
