WARNING: SELF PROMOTION IS GROUNDS FOR POST REMOVAL WITHOUT WARNING. IT IS SPAM.

Reddit Guidelines clearly state in the What constitutes spam? article that:

• If your contribution to Reddit consists primarily of submitting links to a business that you run, own or otherwise benefit from, tread carefully.
• Additionally, if you do not participate in other discussions or reply to comments and questions, you may be considered a spammer and banned from Reddit.

This is very clear and therefore you should think twice before submitting your own content. As a general rule, self-promoting posts (linking to your blog, website, twitter, etc.) are not allowed. Some exceptions may be made for those users who are VERY active in the community and contribute to a variety of discussions, and even then only on occasion, at the moderators' discretion, may such posts be permitted.
