In order to constantly drive traffic to my content from my 500k+, I created this script to randomly select a tweet from a specified set of tweets to be retweeted. The process happens twice a day at strategic times and with randomness added to the timing.
Access to the Twitter API by applying for an app at https://developer.twitter.com.
Create a node app and install the Node-Schedule, Twitter and Mongoose modules.
Create a new cluster at https://www.mongodb.com to store and retrieve tweet IDs (I like to use a set of 20 to 30 tweets to be randomly retweeted. Therefore it's convenient to add a description for each tweets in the database).
