Pinboard seems to be minimally maintained. I've tried contacting the developer (it is just one guy) and have had no response. A bit concerning, if you ask me.

I have seen him being very responsive to paying customers and his charges are reasonable. However, it seems he did get deluged with delicious users whining at him after he saved that service, and you wouldn't reasonably expect a one-man business to be able to handle that.

You could always try tweeting him. He's also on HN.

Eh, I moved on. I paid for a year, but decided I didn't want to invest too much in a service that seemed more likely to vanish than others.

You can always try Pocket. It's both mobile and desktop browser base, and supports search and tagging. Oh, and it's and it's built into Firefox now.

DISCLOSURE: I work for Mozilla, and Pocket in particular.

Thanks...since Firefox Quantum blew me away the other day, I have been playing with Pocket. It's actually pretty cool.
