The quick post module does not allow # tags and @ mentions, and if a user enters # or @ in the quick post then it is stored and rendered as a plain text, this defeats the purpose of quick post.
I had highlighted the shortcoming in
This Link, and you had mentioned that it is in the works, but it seems that this issue has slipped your mind.

Hi Sunny,
Thanks for the heads up on the issue. I believe our developers is currently working on the update with quickpost module and hopefully it will be ready in the next release of easysocial. 
This has become a little urgent as i've done a language override (Share whats on your mind..), whereby i request my site members to use #HASHTAG to tag an item.
Would you please please incorporate this and share the progress.
regards
