Link Shortner Free Short Url Service

Short URL aliases are seen as useful because they're easier to write down, remember or pass around, are less error-prone to write, and also fit where space is limited such as IRC channel topics or email signatures. Also some email clients impose a maximum length at which they automatically break lines requiring the user to paste together a long URL rather than just clicking on it. A short URL alias is much less likely to become broken.
