Bob...

There are a variety of google,adsense,ebay and clickbank...rolled into one...

And other Types...

Based on a Store Front concept...

They may Look interesting and Easy...

Maybe, to Sell to Business opportunity seekers and business idea Collectors.

Visually, they are too Over-Powering to most consumers...

Too Much of a Mish... Mash... of Niches...

But Store Fronts can work if you "Focus" on Particular Niche products...

Marketing one Product at a Time Using individual Links from within your Store Front...

And then Marketing... Marketing... and More Marketing...

Just like what you Must Do to make most Businesses Work!

Here's a couple similar examples and more business models to be found in Google Land...

Would You? Do You? And other Consumers Actually shop and Spend Money on these type of web sites...

Ok, Maybe Amazon and other Big Names...

Thought I'd post this for others "Thinking" about the business idea...

Just my opinion...
