Imagine being a member of ExchangeTweets and you only having 80 Twitter followers.
Jason, also a member of exchange tweets has 70,000 followers.
Jason wants to advertise his newly created website and is looking to spread the word with a tweet.

In order for Jason to have his tweets/content displayed and seen by others he must share
your tweets with his followers. In return for sharing your tweets Jason
will earn credits so that his tweets are displayed to others.

Without Exchange Tweets, you may never have the opportunity to share your
advertisements/content with Jason's 70,000 + Twitter followers.

Now what if 20 members with 5,000 + followers each share your tweet?
That would mean huge traffic and more social network exposure for you!
