I am a student (again ;-> )

I have started my first formal online tutoring course with Oxford Brookes. I have attended many workshops (both online and face-to-face) related to different tools, techniques and approaches to e-learning and e-tutoring, but most of them were 1-4 hours long. This course lasts 1 month and the most exciting thing so far is the fact that the groups is so diverse in location and background.
There is another great point about this course - it encourages the use of a learning diary, which is a great news for my blog - finally I will give a higher priority to this little 'corner' of the virtual universe and will make time to post on a more regular basis. My major reason for not writing here as often as I want is that I still struggle to find the balance and the right approach. Currently, at this very quiet time (in terms of teachign responsibilities) I have 2 blogs within the University VLE, one for my online students on Research Methods and another one as a member of the BU community (OK, in fairness, I has posted only a couple of messages there, of which one was to direct people interested in my life and posts to this blog). I have resorted to maintain separate blogs for the benefits of my students - I am sure they would either be confused if they see a comment that relates to another course, or would have to sieve through a lot of other posts that are nor concerning them prior to finding some useful for their unit post. Yes, I can hear the comment that they will learn more from reading other posts, e.g. the Diigo one, but the reality is that my workload will increase due to the number of questions/complaints on the difficulty to use this source of information. And, yes, I have given due consideration as to whether discussion boards and announcement boards could not be used for some of these details, and the answer is that blogging is the best option. With 180+ students on some units and 4+ units to teach + a general research blog as part of my day-to-day life, I am trying to find some pragmatic and effective way of managing these blogs.

Any advice from those who are familiar with this problem and have found their optimum solution will be very welcome.
[OK, sadly, it's time to stop and get kids ready for school. They need to be there in time and the most frequent cause for this goal being missed is me and my work. If there is anyone that really works hard and has achieved some progress in improving my time management, these are my daughters. Setting all watches 4-5 min ahead does not help in my case... Time for coco pops :-)]
