Introductory topic about online investors

After the section on Internet investments conducted by me at SPIC-2007 and the questions asked to me, I decided to break up the material about investments in the Internet into several small topics:
1) What does an investor want?
2) How does an investor determine the prospects of a startup?
3) How can a startup communicate with an investor?
4) Loan or investor?

If readers have more questions, new topics will be added. :)))
