Links on blogrolls, especially among a network of blogs relevant to your topic, are very good to have - though you`ll need to reciprocate a bit not only with links, but with good content to maintain your presence within the blogosphere of choice. Basically, start a blog, keep it up to date with good content, and find out who else is of like mind, is discussing topics you`re interested in, or supplements your information with some of their own.
By the way, it might be difficult to maintain a tastefully and fun "business" theme with the keywords and key phrases you`re likely to deal with, without showing up in search engines surround by undesirables - all the more important for you to create and promote a series of articles and discussion around your product, its benefits and target client usage and lifestyle, using words and phrases you think would be valuable and leveraged by your customers and business partners (vs. those that might pop up in related spam). Control your own media and search engine listings!
