Cyberian was being a smartass, notice the smiley at the bottom? Nothing wrong with not posting 20 messages a day.
Most general web stores are failing because they all sell the same "stuff," and given a choice Jane Consumer will buy her MP3 player or game from Amazon instead of "Bob's Komputer Hut."
Many specialty web stores failed because they wildly overspent on advertising, lavish offices, web site development, loss leader prices, etc. expecting that their sales would grow 100 times last month's forever.
I'd say to your friend to take a hard look at what other competing stores are already online and whether he can really offer something unique. Carefully figure out how much must be sold to break even after figuring out all the costs including advertising, website design, updates, and server hosting.
