New rails site. Beta testers need


Hi Rails L.,

I need some beta testers for my new site: This
is literally the first group to see it, so be gentle.

Smarkets is a prediction market for Amazon products. It takes Amazon
products and turns them into a stock. The price of these “stocks” move
on the movement of its Amazon sales rank. If the sales rank goes up 10%,
price of the stock will go up 10%, for example. The goal is to make
trading the movements in these stocks.

It is best explained with an example. Here is the Agile Web D.
Rails book:

Here you’ll see a sparklines graph of the sales rank of this book, its
current sales rank 755, and the current smarket stock price $7.14.
the $10,000 you get for signing up, you can buy or short this “stock”.
the sales rank moves up 10%, then the price of the stock will move up
If the sales rank declines 10%, then the price will decline 10%. And so

There’s also tags (of course) where you can group products together and
compare them with other tag groups. For example, here is the Rails tag

On this page, if you click on the “compare” button and type in “Python”
can compare the performance of the Agile Rails book with some Python
books I

You can add new “stocks” to the system on this page:

I am very interested to get feedback and ideas from you. Thanks for
it out.
