Using the Twitter API

The microblogging site with the funny name is one of the hottest web services around.

Twitter is one of those websites with very little room for functional nuance. Its limit of 140 characters per post forces users to be succinct, something that makes many people feel over-constrained and leads them to view the service as too simple to actually be useful. Others see unbridled freedom inside such a unique limitation and embrace it like a poetic device. The lesson: You either get Twitter or you don’t.

Regardless of how you feel about it, if you’re looking to try out an API for the first time, Twitter is a great place to start.

Impressions

“Impression” is industry parlance for an actual ad viewed.

For example, there’s an ad on this page, so you’ve just accounted for at least one impression. Why thank you! Of course, it’s next to impossible to know if someone actually sees a given advertisement on the Web. After all, a user might not scroll down far enough to see the ad, could be surfing with images turned off, or might press Stop before the ad is fully loaded into the browser window. This can make impression-counting on the web a thorny endeavor, but then the same goes for other media as well (who knows whether people are actually watching the commercial or off in the kitchen getting another beer?). Short of guessing, you’re probably better off slaughtering a goat and examining its entrails.
