Hang on, what's wrong with linking to blogs on other parts on the site if people are asking for information and the blog post answers that? I'm thinking the arts and crafts section, where I have got lots of information and help via people linking to their and other people's blogs and where I have also linked my blog for people who have asked. I tihnk within the arts and crafts section people should be able to link to blogs, their own or other people's.
OMDB I think that it is ok if you are linking to a blog with the intention of helping someone out - there are sometimes links that have only a tenuous link to the thread that seem more to be about advertising the blog than actually assisting the OP.
Does that make sense? I am never sure whether it is ok to link to my blog as I don't want it to seem like I am advertising it.
