It just seems like the content and tone of messages on each site are different, and thus a cross-site broadcast becomes more bland

Ping.fm Plurks do tend to stick out like sore thumbs around here.

agrees.. and why would people bother responding if it's just a broadcast? Seems less likely the author will check back for conversation..

I stopped using ping.fm for a while. I like each of my sites to have different content.

uses ping.fm for things she REALLY wants people to know. Plus it's easy when she's on the go.

uses ping.fm to broadcast to several services including twitter & plurk, but only actively monitors those two. It's the pinging to tumblr...

that is annoying her, maybe if mymotivatr was actually active she's have something to reblog

I use PING.FM to update status but then check the individual services to continue the conversations as they go different directions.

I use Ping for generic quick updates, but customize personal ones depending on if it is Plurk, Twitter, or Pownce.
