I am seeing more and more of these from people that I know and they are trivially easy to set up. Historically, it was something I only really saw from people in academia. They will usually include a picture, their biography and stuff like their hobbies, interests, somewhere to contact them and a blog, if they have time. The URL will typically just be their name.
Does anyone have a personal/professional website now? If so, how has it been useful to you?
If you see this from a project manager or policy analyst type, does this sort of mark them as a self-important dbag?
