Even as you define them I think the connection b/w blog (learning) and portfolio (learnt) is dynamic and flexible.

I might blog a draft and then refine it later and post it on my website. But once on the website I still might see the need to edit it later on as I learn more.

I agree with Siemens when he says the half life of knowledge is shortening and so knowledge itself is becoming more dynamic, less fixed, if it ever was fixed

I think blogging starts off as an online diary and only later develops more life through comments and connection with others. Sure, that’s much more interesting but blogging has a static nature too and blog urls are permanent, an important point.

I don’t much like the term e-portfolios and don’t use it, it sound pretentious to me. I keep my more permanent stuff on a static website. No big deal.
