I noticed that I don't see the edit link in a question asked 2 hours ago, but I see the link in other questions, including the ones asked less than 2 hours ago.
Backup software for backing up specific files only
How do I clone a hard disk excluding some directories?
Address Book: Is there any way to move the fields up/down?
This behavior is not the same I note in other Q&A sites where I don't have the privilege of editing posts.
