feels alone when no one responds to the messages that are posted

Most of the time I don't get responses either.

how much do you respond in others' plurks? do you make plurks that people are easily able to respond to? sometimes people don't know how to respond to a plurk if it's too weird or sad.

Sometimes people are working, sometimes they're asleep, sometimes they're in SL, etc

Yep, that happens to all of us sometimes, I'm afraid...

It's rough because if people would respond to your plurks, you would probably be encouraged to plurk more. But when no one is responding, it's hard to keep putting yourself out there.
