Not yet. Though you CAN bookmark on Busy.org, which uses the Steemit blockchain (so all the info in a different outfit). I really love Busy, actually :)

And I also just add bookmarks to my  browser bar for easy grabbing.

If you're interested in Busy, let me know and I'll lead you in the right direction. 

Currently, my computer is sick, so things are a little harder this minute. Hopefully, tomorrow it will be better.

P.S. This IS @carrieallen. I normally use the Chrome Browser as me and the Brave Browser as @transientflowers. Currently, the Chrome Browser has the sickness...
