For once I can report on an excellent initiative from Facebook! I know that they are few and far between, but this is really helpful. When you see an article on Facebook that you want to read later, there hasn't been much that you can do about it, other than share it privately to your own timeline. Then of course you have to remember to go back and read it later, and how many of us do that? However, there's now a 'save' function, which will come in very handy.
If you take a look at your timeline you'll see the down arrow in the top right hand corner, and you can click on that (as you know), and there's now a new option:
If I click on the 'Save' option very little actually appears to happen - the dialogue box just closes. However, if I go back to the menu on the left hand side, there's a new choice for me:
Simply click on the 'Saved' link and you'll see everything that you've saved for later:
There's also apparently a 'Save' option in the bottom right of posts, but I'm just not seeing that. You can't save everything - it really seems to just be articles and posts that are attachments, rather than a person's status update, but it's really helpful.
