Is it bad that I tend not to reply to people replying to my posts? I think if I post something even vaguely thoughtful, I tend to use up all my thinking capacity while writing the post. I hit "send" when I've run out of mental capacity to think about the topic more.

So by the time anyone reads it, I'm off that and onto something else. When someone replies, I read and (usually) appreciate their reply, but don't really have the ability to construct a worthwhile reply of my own, so I tend to just "like" it and leave it at that. I do appreciate that someone's taken the time to read and reply. But I do also feel guilty that I'm not responding in kind.
