I’ll bite.
Until now (and even “now” is still suspect), groups and blogs on Linked-In, IMHO, have been cream-puff societies.

Many Linked-In members are signed-up because they want to be in the mixing pot if somebody else is searching to hire somebody like themselves.
For them, this may be a dubious place to declare a position on anything other than softballs and creampuffs — and, oh yes, here-I-am-won’t-somebody-gimme-a-better-job?
Not that there’s anything wrong with that. It just doesn’t inspire the vigorous interchange of ideas and information.

But then there’s this crack, thebloggersbulletin, which allows you to deal with the format of blogging while keeping safe distance from content, issues, and positions one may have occasion to regret later.

So maybe that’s why. What do you think?
