It's true Gilgal1 that “new” technology takes time to be totally accepted.
Here in Victoria we are not required to have a notice board. And we have never had one where I live. So our blog introduced something new that did not even exist before. At the time I also suggested a notice board as an alternative but several owners objected because they thought notice boards were generally unsightly and we'd need two of them because we have two buildings with separate entrances. Notice boards are not much use to non-resident owners or managers, agents etc either . And a blog can also present so much more information.
Residents don't need email or even their own computer to use the blog – although clearly it helps! They just need to be able to access the internet from somewhere (or know someone that has access to it). In reality, all 12 apartments in our buildings have easy enough access.
It took about a week to write all the information on our blog. But once done, it stays reasonably stable. For us, our blog is more for information and not really a discussion forum.
