Be genuinely interested to hear what others think about this. I have contacts who do this (often sharing links) and it makes me cringe - I'm quite capable of discovering my own news - and I find it a bit too attention-seeking. I tend to hide such people. But, I am a grumpy old man these days :-)

I would find original content, infrequently posted and of decent quality, much more impressive.

I guess like so many other things this can be done well, or done badly, and there's a skill in doing it well.
