How do I feel about blogs

I definitely liked looking at the different blogs out there and seeing the information available. I have a few concerns about blogs. My biggest concern is security. Not just for my students, but for myself also. I have family members who are in a huge mess/fight because they have had their identity stolen, and I have seen what can happen to people. These family members are not even computer/internet users, at all. So I worry about exposing myself and my students. My other concern is availability. I know that students have different levels of access to the computer and internet. I have students who have phones with everything all the way down to students who have no phone or internet access outside of school, unless they go to the library. So I worry that students will not have equal access, therefore hurting those students who cannot get the access that the other students can. I can easily see already how the children from homes where their exposure is limited seem far behind those where it is not. My other issue, is for my own children. While I do not mind them spending some time on the computer/i-pod/video games, etc., I am not comfortable letting them spend hours on end electronically tethered to the world. When they are, they are not outside moving, they are sendentary.......and tend to want to move from the computer straight to the tv. I also feel that it inhibits their interactions with people on a one-to-one level. Having a back ground in Speech and Language Pathology, I know how easy it is for one to loose social communication skills. My son already has some issues in those areas, and I do not let him spend a ton of time on the computer, etc. The more time he spends absorbed in these things, the less time he spends interacting with others, which will only further inhibit his growth. I think as time goes on, and everyone has more equal access, I will likely feel better about some of it. I will always be vigilant though with my children. I feel that I have to provide them access to the technology so they can function in this world, but my job, first and foremost is to protect them.
