Too late, LinkedIn has already become kind of a Facebook+Twitter mixture now…

read my comment again. It was not my choice. The people I mentioned were/are only on Twitter, it is either endure their non-work drivel on Twitter, or lose everything they say.

Above all, what I report is just an example of a general problem anyway. If they were only on LinkedIn, and mixing one work-related post every 50 about what cocktail they had last Saturday, what would "wanting LinkedIn, not Twitter, change"?
