How to Tumbl
1. Go through all the posts since your last visit, liking & reblogging as necessary.
2. Refresh your feed to see what was posted while you were liking/reblogging. Like/reblog as necessary.
3. Repeat Step 2 until you either are all caught up or, more likely, can no longer feel your butt.
4. Spend a few seconds off Tumblr.
5. Return to Step 1. Repeat infinitely.
