Hehe, on Steemit itself...all you can do is bookmark. I have a few folders on my browser bookmark bar labeled 'stuff to read', 'resources', etc FULL of steemit links. Lol
However, this is where places like @chainbb can be quite hand to 're-find' things as well as @good-karma's eSteem app which actually has a 'favorites' button available. :)
Thanks a lot
Also, since you've commented, you can always click on your own comments (on your blog page) and scroll down to find this thread. Click.
Also good advice.
Great point! Thank you!
