TwitZip is a service that will let you hyperlocalize Twitter. By keying in your five-digit ZIP code you will be able to receive news specific to that region only.
This means that if you want to know what’s happening right in your backyard, you simply submit the corresponding ZIP code and you will have a contextualized twitter feed from that point onwards.
What’s more, the site has partnered with GroupOn. This means that the fact of you specifying where you live will also translate in you receiving the deal of the day as part of the information that will start to populate your feed. And a partnership with Outside.in means that you are also becoming served with content culled from blogs that are connected with the ZIP that you have provided.
So far, the emphasis is on providing users with information connected with news and crime. The company has already announced that it is focusing on weather and governments alerts now, and something good about this site is that there is no limit to the actual number of uses that it could be put to.
