Twitter is excluding the “@” from its post
 

I have read in Search Engine Journal that twitter is just launched an app, in which it is testing the experience of the user and also checking the usage, without @ tag.
Does anybody know more on this issue, please share your information here. And Let’s see, whether it is a change for good or turns out to bad?

I hadn't heard of that. I wonder what they hope to gain by the change.
