Twitter has improved its algorithms of Trend to deliver tailor Trends, personalized topics based on your location and who you follow on Twitter. Trends generally help you discover emerging topics people are talking about on Twitter. Twitter says that the new Trends lists are tailored for you by default on twitter.com and mobile apps like Twitter for iPhone and Twitter for Android.

If you don't wish to see tailored Trends, but instead want to see a more general list of Trends, just change your location on twitter.com.

Anytime you want a glimpse into the conversations that are happening on Twitter around the world, you can also select individual countries and cities to see Trends in those locations.

Tailored Trends are rolling out gradually starting today. No security breach

Seperately, Twitter said that all the users accounts have remained secure despite claims of the "LulzSec Reborn," hacker group that they have obtained the credentials of 10,000 Twitter accounts after hacking a third-party app.

The group of hackers posted a note on PasteBin over the weekend saying it had posted the passowords and other credentials of Twitter accounts by hacking an app called TweetGif.

The group posted a user table from the app, which included users' Twitter handles, passwords, names, locations, bios or avatars.

Twitter spokesman said all Twitter account passwords remain secure and that Twitter's systems were not breached.
