The one that hit home for me was a complaint about PRs who want journalists to follow them on Twitter, which adds:
"Show me the PR who can say something meaningful in 140 characters and I'll eat my shorts."If a PR could condense what they had to say into 140 characters they wouldn't need to contact the media about it. If they could say it that concisely they would have a message.
A message spreads itself. It finds the people for whom it's of interest. Sadly for the PR, that's never quite enough for the client, who really ought to consider advertising. Instead they take that money and spend it on a PR, thereby doubling the irritation the journalists feel. More pages to fill, less budget to fill them with, more people "reaching out" and wanting to "touch base" with them.
