"Note that this release is read-only version of Surfer, meaning you can read posts, check profiles, etc. Next steps will be adding more and more features on top allowing everyone to perform operations."
With the rest of the features (posting, commenting, upvoting, resteeming, etc.), this will really be a killer app on the Steem blockchain. Especially when we will be able to collect and use eSteem Points (ESTM) on the web application.
By the way, I approved the XSteem proposal. Congratulations on your works! Keep up the good work!
