I found a way to create a personal diary on the net. Its like your personal journal and even if people know the url, they cannot read till they have access. Thought some of you might like to know.
Step 1 - Create a new blog.
Step 2 - Change preferances for this blog to not appear on your profile.
Step 3 - For the new blog, change preferances for reading options also. Ask for authorisation to read the url. Only people you specify as readers will be able to read the url.
There, as simple as 1-2-3. Now all your personal catharsis can happen on blogosphere too!
