Basically I removed:

-Dead journals that haven't been updated in forever.
-Abandoned journals or inactive ones.
-Journals with no shared interests with mine.

Also, along with the following:

-I comment to your journal but you don't reply to my comments.
-You never or rarely comment on my posts.
-We don't talk anymore.

No hard feelings, I just wanted to sort things out. If you feel this is a mistake, please let me know.
