I see it around on Twitter. A note: “Following, liking, retweeting is not endorsement.”
Now... Following, of course, does not have to be endorsement. You may follow someone for the sake of following, to have an idea of what s/he writes about, to see how s/he thinks. You may also follow someone for the sake of watching out.
As for liking... I do not understand how liking something can be non-endorsement. Seriously, if you like something, doesn't it mean you think it is a nice thought? I mean doesn't the definition of liking imply that?
Coming to retweeting... Which is the most used. “Retweeting is not endorsement.”
Okay. I get it. Retweeting does NOT have to be, is not necessarily endorsement. You may find something outrageous and want to share your feeling with the world. You may find something ridiculous and want to share your thought with the world. You may feel and/or think there is something in one tweet, something that is worth opening a debate on, so you might want to share it. Okay... These are all possible non-endorsement cases.
BUT... You've got 116 characters to comment when you are retweeting. If it is one of the cases above, could you please be not lazy enough to just say something like “This is outrageous!” “This is unbelievable!” “Ideas anyone?” “Seems an interesting point, what do you think?”?
I don't know... Maybe I'm missing out on something here. If so, I'd appreciate if somebody -for example somebody who declares s/he is not endorsing with likes and retweets- could enlighten me.
