Keen to keep its dominance intact and in a bid to become user friendly, Twitter, among the top social networks, has unveiled a series of changes, has undertaken elaborate redesign exercise and has introduced new versions for Android and for iPhone, apart from introducing Twitter for Nokia. To offer users a better experience, Twitter has also revamped search experience. We take a quick look at the modifications brought about by the site in the last few days.

One of the world’s most widely used mobile platforms, Nokia, now promises to offer a fast, responsive, richer and native Twitter experience for its Series 40 feature devices. The Twitter for Nokia for a Nokia S40 device can be downloaded in the Nokia Store. The device users can sign up for the social site directly from their phone, check Tweets from all the accounts they follow, easily and connect with others, and more.

Keen to make real-time information readily available to everyone, everywhere, Twitter recently unveiled a new update to mobile.twitter.com both for older browsers and feature phones. The networking platform has redesigned and revamped the mobile version. On the top level, for example, it has brought the user interface in sync with the Twitter version released in December, so users can have a consistent experience and feel on any device. Also, the view layer for its RAILS backend has been completely overhauled, incorporating new mustache templates plus streamlined stylesheets.

After over two months of extensive work, a mobile.twitter.com has recently been launched with many improvements, such as smaller pages, smaller sessions and much fewer requests in some select views like profile pages. The new versions of Twitter for Android and Twitter for iPhone contain many updates, as follows:

Since the site introduced expanded Tweets, many new partners have been added (MLB and C-SPAN, to name a few) to a growing and diverse list of media sources. Now, users can expand Tweets on Twitter for both Twitter for Android and iPhone. When one taps a Tweet linking to a Kickstarter project, for instance, one can directly play its video from the Tweet details view in one’s app. This whole new experience will gradually roll out to web, iPhone and Android users.

Now users can discover the best of Tweets and photographs for events experiences, such as twitter.com/#NASCAR on their iPhone. Twitter for iPhone now complements any live event, irrespective of from where you are watching from it.

Twitter has made improvements in search autocomplete for more suggestions when members search for people. The new versions also support push notifications for Tweets. Users can receive them from friends and contacts after they send a new Tweet or even Retweet; turn on push notifications for any user via the action button on their profile, and edit the same in account settings on the device. Explaining the rationale behind changes to Twitter search, an official post explains:

“We ae constantly working to make it (Twitter search) the simplest way to discover what’s happening in real time. search autocomplete and ‘People you follow’ search results updates, to twitter.com. In addition to recent improvements, such as related query suggestions, spelling corrections and more relevant search results, will make it even easier to immediately get closer to the things you care about. These updates make search easier on twitter.com, and related search suggestions, search autocomplete and spelling corrections are also available on Twitter for iPhone and Twitter for Android.”

Search autocomplete will show the most likely terms for a query as a user enter it, quite useful if someone is trying to follow the hashtag for any event or while looking for a particular Twitter account. A user can select query from the drop-down menu even before having finish typing it. Once one enters your search, the most relevant Tweets, accounts, articles, videos and images for the query are found.

Twitter has made other improvements, such as spelling corrections, related suggestions, results with real names and usernames and results from people you follow so as to make the whole search experience more comprehensive and better.
