Tumblr is useful when all the things below happen at once:
- Stumbleupon gets arsey with your bookmarking and thinks you are a spammer;
- Twitter decides your sentence is too long for people;
- You want to share something but don't actually think it merits taking the effort to email the link to anyone.
