Duncan raises some good points about the evolution of blogs and microblogs (i.e. Twitter). Blogging is becoming the online publishing platform of choice in many industries, from politics to pharma. This has a couple of implications for influencer programs in 2009.

Top of my list, is that 2009 should see the end of consternation over classifying influencers as “bloggers” or in terms of their other roles in a market or community, be it their job title, employer, profession or expertise.

The crossover point started to become clear in mainstream tech media relations when you could no longer distinguish between columnists and bloggers at ZDNet and other top-10 media networks.

In analyst relations, Gartner brought the point home a few months ago with the launch of the Gartner Blog Network. Trust me, no one is dithering over whether to reclassify Gartner employees from analysts to bloggers.

Sure, some people will be best classified as “bloggers”, just as we still have syndicated columnists from the hardcopy print days. In general though, the confusion over doctor-lawyer-blogger man-thief should die down.
