You might be aware of this already, but when posting to Reddit, make sure to use the appropriate subreddit - in your case http://www.reddit.com/r/bioinformatics, which has 2,790 subscribers. Posting to Reddit generically won't get you anywhere.
If your product has a certain application angle that could be interesting/funny/relevant to larger subreddits you could try to create an infographic hosted on imgur - as cool as Reddit's community is, their attention spans are rather short and most people won't read / upvote a lengthy article (safe specific subreddits, I bet things over at r/bioinformatics are different.) Good luck with your startup.
EDIT: semantics.
