Ask HN: Am I spamming HN if...

My co-founder and I made a submission to HN about 9 hours ago (http://news.ycombinator.com/item?id=2918489) and the response has been awesome - lots of traffic, signups etc. Now I'm thinking what we need to do is keep generating new features and content to justify more HN posts, but does that then devolve into a kind of HN spamming campaign? I'm assuming 1 a day is too much, but we could probably get away with more than 1 a month. Thoughts?
