Just an hour ago (around 1am MYT or noon USA EST, Michael Gray (@graywolf) posted a simple message on Twitter:
"I will give out $100 via paypal to ONE person who is following me as of 12:00 midnight east coast time - please RT"That simple message on a 12-hour contest (from noon to midnight) offering $100 via paypal was enough to generate over 150 retweets per hour (about 2.5 messages per minute), sending a spike on twitscoop, highlighting "paypal" on twitcloud:
To enhance the tweeted message, Michael also immediately highlighted the simple contest on his Twitter Bio.
It helps however that Michael already has nearly 5,000 followers on his @graywolf twitter account.
Expect that he'll add a few thousands more very soon...
