Reading List in other browsers?

All reading list is a simple wrapper around bookmarks, that allows you quick access to both add and remove entries. It's usefulness stops there really, and the matter of convenience boils down to what you want to use the stored pages for, and how you wish to access them. If you are just using the same computer and will always have a net connection, then yes it's very convenient, but if you want to have them stored offline and synced to multiple devices, then it's not so useful.

I don't use Chrome, but I would probably look to get an extension for either Pocket/Readability/Instapaper to mimic the reading list feature, by making your recently stored pages available from a toolbar button rather than having to login to the respective sites. This gives you all the added benefits of using a proper 'service', with the instant nature of a quick bookmark system. A quick search for "instapaper" yielded 50 results on the Chrome extension store thing

To add the active tab in Google Chrome to Safari's reading list:

Adapted from a comment by tzarskyz on: Add a URL from Chrome to Safari's reading list

tell application "Google Chrome"
    set pageUrl to get URL of active tab of first window
end tell
tell application "Safari" to add reading list item pageUrl
display notification pageUrl with title "Added to Reading List"

Open AppleScript Editor and save the above code as a new script. From that point on, you can run this script to add the active tab in Google Chrome to Safari's reading list. You can trigger this action via Terminal (osascript), by double-clicking the script (in Terminal or on your desktop), via an app launcher like Quicksilver, via Fastscripts, etc.

Enjoy your reading! :)

Update: I've since found a better way to accomplish this, without requiring something like Fastscripts. Simply use OS X's built-in application, Automator. You can adapt the steps outlined at the following link to run the AppleScript I included above: Global HotKey for Pause/Play,Next Song, etc.
