Hi, I'm Aliza a BC patient and also a Medical Librarian (retired) who offers research and referrals on this site and elsewhere. I'm also a former technical writer and editor. I hear what you're saying and it seems to be you want something that would be more in the style of a blog.
It's true we don't have a blog here, but there are options here that aren't available on a blog in terms of searching. It's awfully difficult to index a blog so that you can put in a search term and be referred to lymphosarcoma for example.
You can certainly Google to see if there's a blog on Cancer in general (I'm sure there is), but I've got a fairly extensive medical background-have edited for some of the medical journals, veterinary medical journals, my ex husband's a physician, my daughter's a Paramedic becoming a Nurse. I've been learning a lot about other types of Cancer besides BC here. It's enlightening to me-Cancer is rampant in my family (just not BC).
You can also message Greg P to tell him what you mention here. I'm not in Tech Support so I have no power to make changes, but I love this site.
If you want to blog on your own, you must know about wordpress.com if that helps and you can then refer people on the site here to your blog.
I hope you stay on the site and ultimately find a compromise that suits you.
If I can be of further help to you, don't hesitate to message me or email me offsite.
