Linked In vs. Twitter - Where do they merge?

If you're playing in the social media space as a personal brand or business, more than likely you are on LinkedIn (for business connections) and Twitter (to build a following that leads to new customers)...or that would be the basic theories. And this could be argued "100 Ways To Sunday" as to where the two converge. So maybe I'm just so inundated with thoughts that I missed this concept, but until today, I never thought about "Are connections on LinkedIn annoyed by my twitter posts?"

Now, I do not Twitter constantly, but I do a fair amount. And I have my Twitter Posts feeding to both Facebook and Twitter..."but, is that annoying my friends and connections?" I raise this question only because it was brought to my attention by @greigwells during a #SMMU session today on using "Advanced Twitter Techniques." This was part of the series being offered by Social Media Magic University and it really caused me to pause and think..."Are people getting annoyed with Twitter posts being fed to Facebook and LinkedIn profiles?"

I'm curious...you?

Thanks Greig for causing me to pause and think about this!

So everyone else...what's your thoughts?
