Demands of blogging

We had a great Professional Development session today. We talked about the current trends in e-learning and what is happening in schools today. I really enjoyed some of the thought provoking discussion that took place because it let me evaluate what I am doing in my classroom. My current challenge is this whole blogging thing.
At the moment I find it difficult to find enough time in a day (as well as energy) to do all the things that I want to do. Blogging for my self is something I need to get into the habit of doing. For me that will come with time. What I have been thinking more and more about lately is blogging for kids.

I use kidblog with my class (http://kidblog.org/Room265/). Please come and visit us by the way, the kids love to see your comments.

I have some children in my class who have a number of dyslexic type needs (I don't want to label them as dyslexic because it is such a huge range of difficulties that fit under this very large umbrella we call dyslexia). These students often dislike writing and reading. Blogging is a great tool for them as they don't have the negative connotations with computers as they do with pen and paper, which is usually a struggle. I realise that not all children will jump up and down about blogging, but I have realised that some of my children have started to write about their day quite regularly. The comments they write to each other are becoming increasingly more constructive, rather than just "cool" or "nice story." Some still have some growing to do in that sense but we are getting there. This has also been great for my really bright kids because they feel like they are educating the people around them by writing interesting facts. Some of my boy's write a fact each week. They have to find a new piece of information, learn about it and blog about it their own words (NO COPYING!) So over all this has been a very valuable tool to increase children's confidence and enjoyment for expressing their ideas in the written form.
This brings me to my dilemma. I use kidblog to keep an eye on what the children are writing and help out some of the children who struggle with spelling by checking some of what they write. I don't correct all mistakes, I think it is important for them to make these and discuss what they have written with their peers. What I'm finding now though is that I can't always keep up. During the term with all the other things we have to do (MARKING, updating wikis, collaborating with children on their google doc creating flipcharts...) I am finding it harder and harder to make sure that I check each blog and approve comments.
So here is my question to my fellow educators... How do you keep up with the increasing demand to keep blogs, wikis, sites, etc up to date? What do you do to manage these? Am I being a little too ambitious by checking all these blogs?
What are your thoughts on the matter?
