Washington, Aug 18 - The social micro-blog website Twitter has been carrying out experiments changing the way 'favorite' feature works, leaving users disappointed.

However, the experiment has back-fired the website as users are not very happy to see lesser tweets on their homepage.

The website now shows tweets and retweets posted by accounts that one personally follows. Some users are seeing a few tweets in their timelines that have merely been favorite by accounts they follow. Other tweets are showing from accounts that your friends follow, The Verge reported.

The experiment is concerning people as the 'favorite' feature is not as widely used by users. The feature is treated as a simple acknowledgment of receiving a tweet or as a way of saying 'thanks.'

It can also be a simple way of saying that you found something funny. Others use it as a type of bookmarking system. (ANI)
