I sense your pain David, but I have a slightly different perspective 🙂
I really don’t like Tweets that ONLY promote a company’s new bells and whistles. I seek a more authentic voice and value those Tweets that occasionally mix business with pleasure. As an example, I follow some industry folks who Tweet about music they are listening to (and have discovered great new tracks that way). imo it grounds the person and right or wrong, I think I can better judge their promotional posts.
I just don’t trust relentless self promotion – and it wouldn’t help to have two accounts, as I don’t want to do the sifting myself. I simply want a mix of entertaining AND informative messages.
I gave what I hope was an excellent presentation (modesty escapes me) on the realities of social media which can be found here:

fwiw – I hardly every visit LinkedIn nowadays as it seems too blatantly about self promotion. I use Facebook for friends and family, but post via Twitter, and use Twitter for biz+pleasure.
To each his/her own. Oh – and I enjoy your posts!
