title: MongoDB Collections
body: <p>I am in the middle of developing an app which harvests tweets, Facebook statuses and Facebook photos for a user. Currently the user sets out exactly when and to they want this harvest to occur and a spider pulls the data during this period. The when and to is stored in a MySQL db and my plan was to store all the tweets, status and photo meta-data in MongoDB (with the actual images on S3). </p>
  
  <p>I was thinking I would just create one collection for each of the periods the user wants to harvest for and then store all the tweets etc from that period in that particular collection. </p>
  
  <p>Does this seem like a reasonable approach?</p>
