Apart from delicious any tool to track urls for read later?

Something that I come across browsing on a system at my friends place or at work, but really want to come back to it when I am home. Some URLs I want to bookmark and some mark them to read later.

If you want to try my home made exercise and comment on it, you can check out www.markmyplace.com It is an alpha but I actually use it and will respond to feature requests and bug reporting.

I switched to Pinboard from Delicious about two months ago and I'm very happy. The Firefox plugin works and continues to work even with FF 10.

I switched to PinBoard when the slide about "sunsetting" Delicious was leaked. I've got the archive plan which has worked wonders since a few bookmarked sites have died since then.

I have it tied to my Twitter account. Now anytime I retweet a URL, the URL gets "pinned" to my account and marked "unread".

In addition, I use Instapaper since it's integrated to various iPhone and iPad apps. Pinboard also imports anything from your Instapaper feed, so it becomes the end-all be-all for my bookmarks.

I starting using pinboard about three or four months ago. Best $9.51 I ever spent on the net.
