Thanks for asking.
1. I've been registering and selling specific domains since some time now. I don't do it in a disciplined manner as I used to however. I don't buy and flip. I register and flip.
2. I've been putting in 2 hours a day behind international chatteling.
Wrote a post on it sometime back:

It is doing really really well.
If I had to sum up why I succeeded, it would be: because I found an awesome untapped marketplace - a constant source of buyers.
With chatteling, you have to find the buyers before you go and find the sellers - and procure the goods to sell.
Since my post, I've seen a couple of competitors come up too - but surprisingly, sales haven't gone down. The market is growing faster than the competitors.
3. I have been earning from infoproducts since a long time, but I've never dealt with amazon yet. This will change over the next month as I am funding an amazon / kindle project. Hopefully it will do well - but too early to say.
Want a sneak peak? Send me a message - I would love some early feedback too.
