I have a website which is going to show my shareware, another site for my blog. I will post all my thinkings/development tips/design tips/business experience on my blog, but most of them are not related to my shareware. Software users may not interested in my blog. In this case, is it still better to host my blog to another domain?Thanks.
blog.domain.com(domain.com/blog) or another-domain.org

Depending on just how disjoint the blog posts are from the shareware I would create a new domain for the blog. Then I would use specific tags on posts about the shareware and use a tag RSS feed to put those posts into a news section on the shareware site. Doing this would give you the flexibility to have multiple sites pulling from your blog on different topics. If someone really wants to see all your posts they can click through to your blog from the other site.
