Youtube – Replies to the comments

You may have two logins with your account—e.g. you may have Chrome and IE and have logged into them both at the same time; doesn't matter if one screen is closed because you are logged in online.

If it still doesn't work, I can’t help you but when I started to use Chrome, I had my YouTube on IE still logged in and the inbox notifications wouldn't go away until I looked at them as well as the ones on Chrome. After you do that, log off your leased used browser and that's it. This is just my experience.

You could find your comment by using binary search and changing the url manually:

1. Start by getting the time of your comment from the activity log. Then go to the post and press on the time-and-date-text below one of the comments. The URL you go to should look something like this:

   https://www.facebook.com/{page}/posts/{postID}?comment_id={comment_id}&offset=0&total_comments=1000000

2. You are looking the offset for your comment, you know it should be between 0 (lower bound) and the number of comments (upper bound, In this case 1 000 000). Offset 0 means the newest post and 1000000 is the oldest post (in this case).

3. Let L denote the lower bound of offset, U denote the upper bound and M half way between L and U. (M = (L + U)/2)

4. Remove the comment_id from the URL and change the offset to M. The URL should look like this

   https://www.facebook.com/{page}/posts/{postID}?offset=M&total_comments=1000000

5. Look at the time on the comment there and compare it to the time of your post.

   • If your post is older, then the offset is to low. Let U = M and calculate a new M.
   • If your post is newer, then the offset is to high. Let L = M and calculate a new M.
   • If your post is from almost the same time, just press "Show more" until you find yours.

6. Go to step 4 and repeat until you found your comment.

This should give you the your comment within log2(1000000)=17 iterations, so even though it is complicated, you should find the comment a lot faster.

To find your comment (even) faster you could use the time difference to guess something between L and U other then M.

Optional:

Let t_L denote the time difference (e.g. in minutes) between post L and post U, and t_Y denote the time difference between your post and post U. Then the following formula for M should find your post in very few iterations (1, 2, 3 depending on how evenly the comments are spread):

M = (U - L) / t_L - L

But it probably won't save you much time because it is complicated to calculate the time difference in minutes.

If there is not a million comments you could probably skip the binary search and just guess from the time difference between the first comment, the last comment and your comment instead.
