I believe the subscription made the whole site lag, but it would be cool if it the optimization changed
When I find a cool thread, I just copy and paste its link on a .txt folder.
You can call the folder "Threads to check" or whatever you would like
Hope this helps.
best tool for managing your links n stuff

This has been discussed already.
In the mean time, if you want to see if any threads that you've posted have updated posts do this:
Click on your username, then click on "Find all posts" and you'll see the "new" icon by any thread you've commented on that has updated posts.
You can do the same for threads you've created by clicking on "Find all threads"
Semi cumbersome if you have many posts, but it's fairly quick to breeze through them form most people.
