I usually bookmark such threads using Delicious. If the title has something meaningful, it’s easy for me to find the bookmark later. Using Delicious is easier than having bookmarks on local browsers. You could sync bookmarks via MobileMe and Safari, but this is another approach.
By the way, here are my Logic marked bookmarks over at Delicious, in case anyone wants to check them out — another nice thing with Delicious is the option to export the bookmarks.
Also, if you are a serious Logic user, I can’t stop recommending reading LogicProHelp the forum from time to time.
