With Buffer all you do is put a few tweets in your Buffer and the app schedules them for you throughout the day.
Different from common tweet scheduling apps, like Hootsuite's or SocialOomph's there is no need to schedule each individual tweet. Fixed timeslots (which you can change) determine when buffered tweets reach your followers every day. All you do is fill your Buffer with tweets.
In addition to using the website, browser extensions make it super simple to add tweets to your Buffer right there from the article you want to share.
TweetDeck is a social media dashboard application for management of Twitter accounts. Originally an independent app, TweetDeck was subsequently acquired by Twitter Inc. and integrated into Twitter's interface.
