There was an anonymous comment posted at Yeranen Yaakov, which sums up why it's important the blogs continue....
If you've ever been unwell and stuck at home, the internet is a life-saver.
If you live in a part of the world where you have no synagogue, community or rabbi, again the internet is your life-saver.
I know what it's like to be stuck at home because for several years I was, due to a major illness which B"H has pretty much disappeared now. I also know what it's like to have no rabbi available to ask questions, and so I use the internet rabbis, without whom I'd be in big trouble. Thanks to all of you who answer me..... much appreciated.
