jumping into existing comment threads as the equivalent of spotting a group of strangers at a party and diving in
But this happened all the time on Tumblr when posts from someone who wasn't on my dash were reblogged by someone who was on my dash, and I reblogged or liked them or added a comment. I understand you feel it's very very strange to "go over to" someone else's DW and comment, but it's not considered gatecrashing or invasive here. If a post is public, unless the comments are turned off or screened or otherwise moderated, it's pretty much taken for granted everyone can comment. Which atually is not that different from how Tumblr works. I think you're struggling much more with your own perceptions of how DW works, than how things actually are here.
