You should try out https://filepost.io (Disclaimer - I own it) I do feel for zippy though. Even for my site, Ad revenue has completely dried up and infrastructure costs now outweigh my revenue.
I run https://pixeldrain.com. At the start of this year I completely removed all ads from my site. I'm done with checking ad network after ad network only to find out that they all pay the same: pennies.
Pixeldrain now runs on subscribers over at Patreon and it's working quite well actually.
You can shop around for bandwidth even if you're a small shop. I run https://filepost.io. It lets you share large files and images. It is profitable with ads alone.
took a look at it, nicely implemented resumable uploads/downloads... very smooth.
i notice youre using cloudflare to deliver the files on the download side, and im guessing you are taking advantage of bandwidth alliance so ingress/egress are basically free - i always thought the biggest cost for something like this would be the storage, eg if you are letting people send unlimited <5GB files for free, and each of those last for 10 days on what im assuming is some kind of object storage/s3-like thing, surely you are paying a fortune in $/GB/month, even if its pro-rated to 1/3 the amount since the files only live 1/3 a month?
This is extremely useful! If the product is solid, this would easily replace 4 subscriptions that we already have. Good luck with the release. How do you plan to price this?
Just released https://docstamp.io which lets you notarize documents on the Ethereum blockchain. To make it accessible to the wider audience, I accept payments in USD. I have a FAQ which has a link to the contract. I’d love to get some feedback on the site.
Incidentally, what do you think about dynamic favicons [1]? They're a fairly simple feature to implement, but a useful one. In your case, they'd let otherwise-useless favicons be status indicators themselves (which makes sense for anyone opening/refreshing a tab anyway) if they so chose.
Plus, it'd let your users promote their branding (upvote/downvote icons in that specific case) which is a win-win.
At minimum, some custom title text ('[user's main offering] is up'/'down' etc) would make a lot of sense, but I really think the favicons are simple enough (both to implement and to understand) and visible enough to be worth it too - it'd allow for at-a-glance uptime information [2].
