I have come across a Cool Twitter interface TwitZap - which offers nice features which just might drive your attention into it. If you are not interested in switching to standard advanced Desktop clients like Tweetdeck, then Twitzap may be worth a solid choice.
Twitzap, web based Twitter client focuses mainly on 3 major features.
1) Unlike Twitter, Twitzap Automatically updates/refreshes the page in real time. You can also pause the tweets by just turning on the knob which is on the left-side. This is a good improvement from standard Twitter page which needs to be manually refreshed all the time for latest updates.
2) Twitzap claims that they help you Tweet very fast(under 800ms) even though Twitter is slow or down.
3) Unlike on Twitter where you need to click on the username in the menu on the right side to look for all the mentions on that username, Twitzap helps you to do that for any term you want. You can add any channel into your list.
4) It also provides a shorten url's button to make short-urls of any lengthy url post which we can't find in standard Twitter interface.
5) clicking on Retweet button of any post copy pastes the entire message for Retweeting which is another cool feature can't be found on normal Twitter interface.
