Ask HN: What are your thoughts on reposting?

I write in a data blog a decent amount, and really think readers here would like some of the posts and find them interesting. It's just so tough and decently lucky to get a post upvoted in the first 15 minutes or it gets lost.

Don't worry, not trying to get publicity for what I wrote here, just wondering if trying to repost an article a few weeks later would be reasonable and not looked down upon.
