I see no problem in having a weblog as part of a class.  I see them as being a easy way to connect with students, and could even be easier than setting up a webpage.  Having a blog would provide for an easier class discussion I think than a regular website would allow for.
As far as the article, 'Should "technology integration" be an important goal in schools?', I agree with Mr. Cunningham.  I think that technology within education is a good thing but only to an extent.  I do not think that giving schools money for more computers is always a good thing, because when that happens then other areas of the school that need money fail.  Technology is important but should not be the number one concern on a schools list.  Computers do help teachers as well as students in many ways, yet at the same time can do harm.  Students know how to do EVERYTHING on computers, yet hand them a sheet of paper and a pen and they think that you are crazy.
Computers are good to have when they are used properly.  Yet, as we have seen many times, students do not use computers just for school work, they are browsing the internet and talking to random people that they do not know.  Technology should be integrated into a students education, but lets not forget how we started off in education, pen and paper and blackboards.
Leaving everything up to a computer sets us up for many problems.  What happens when the computer crashes, and all of your work is on there?  What are you going to teach to your students that day?
Let us integrate technology into a students education, but at the same time still be using our old methods of teaching!
