This was one of my smaller ideas - the ease of Posterous combined with the single-designed-page feel of about.me (and others like it). For a long time, I was looking for somewhere suitable to write up a restaurant review or talk about a movie or share something else, without committing to a full-scale blog.

No next or previous post buttons, probably no comments, just a title and body. Then a pool of photos/themes to present your information nicely. No feeling of abandonment or fear of commitment.

Not sure without further thought how this could be taken to the next level, but it's at least a nice side-project worth trying.
