Is it ok to post a link to my blog, within my post?

I post short reviews of products that I buy from the BST section, in my blog. I was wondering if it will be ok for me post an excerpt of the review in the product thread itself with a link like "read complete review" to my blog post.

 

I would consider that link spam if you're doing it repeatedly, as you're doing it more for the links than to add value to members. Absolutely do not start new threads to post reviews. If you're posting them in a deal thread you took part in, you should be posting your feedback directly in that thread if you want to leave it - not just abbreviated thoughts telling people to go elsewhere. Reviews are one of the few allowed types of responses to sales threads solely because they add value to everyone involved.
