Blog, why bother?

Its a lot better than keeping a diary and its easy to share, but, you can never be sure if anyone actually reads it, many the time I've mentioned something or discussed photographs I've posted with my sister Yvonne, "I've not looked today" she will say, this is possibly about something I posted two or three days ago! Or, maybe thousands are reading about Half Acre Farm, but no one is commenting, or very few are following the blog, now I'm as guilty as everyone else, I read a few blogs regularly and others occasionally, but often forget to comment, even just to say, "OK read it", so if you are reading this please tell me, you don't need to critique if you don't want to, just so I know that I'm being heard.
