If you do have linkbait, whether by design or by accident, make sure to capitalize. When you hit the front page of Digg, Reddit, Boing Boing, or, on a smaller scale, attract a couple hundred visitors from a bigger blog or site in your space, you need to put your best foot forward. Make sure to follow up on a high traffic time period with 2-3 high quality posts that show off your skills as a writer, your depth of understanding and let visitors know that this is content they should be sticking around to see more of. Nothing kills the potential linkbait "bump" faster than a blog whose content doesn't update for 48 hours after they've received a huge influx of visitors.
