Ask HN: What are some free startup ideas you wish someone would just build?6 points·by supergram·3 ปีที่แล้ว·2 comments
supergram·3 ปีที่แล้ว·discussTwitter has 400m users. At $8 that's $3.2b/month, $38b/year. This might be a decision most social networks didn't take, and an unpopular one, but if it works it can have massive payoff.
supergram·3 ปีที่แล้ว·discussre P.Thiel: I experienced the same thing on HN.I would welcome HN providing visibility into the nature of the downvotes (how many up total, how many down total, when).I also want to know why something dissenting/controversial/unpopular is downvoted.
