No, it isn't just you, unless the 'Edit' disappears immediately. I can still edit my posts for a few hours, then it disappears. Unfortunately, I continue to find typos and grammar errors well after that, when it is too late to fix them.
O.K.: I see what you mean. I DO have the button on my post above, but I found a maddening typo on a few days old post. Oh, well.
yep, as fuzzy said, it's a pain. not sure how many hours they give you, or why they changed it. it's a real problem for people who post charts and things they want to keep updated as new data comes along.
I was speculating it was if someone like'd or quoted your post, that would close it to editting. Or just a time limit? Notice also: no "like" button in Fred's House of Politics, probably for the best.
