I'm still having a few issues with with pinboard I'm starting to regret leaving delicious.

For one the autocomplete on the bookmarklet will only suggest about half of my tags. Also the add a note feature doesn't save the text of the note. I haven't heard back from support.

We're usually pretty quick with support, although it has been a bit of a crush lately. Feel free to email again (or simply email, if you tweeted, it's really easy to miss a tweet).

The way notes work is a little odd for historical reasons and needs cleaning up, you can search the dev list for a more detailed explanation. It does save the text of the note, though.

Either way, sorry for the delay and drop us a line with your questions.

I'm glad I made the switch - pinboard seems much more responsive, even during that massive spike. The only thing that took a while was importing my bookmarks. That's more than understandable - how many bookmarks were imported over those few days?

Maciej's write-up will have accurate numbers but it was a pile. Something in the 7 to 10 mil range for the first 36 or so hours.

I'd love to see a graph of signups during this time. The article says "not a whole lot of Delicious users switched to Pinboard"--is this true? I wonder how much the signup fee dissuades people.

The signup graph pretty much tracks the traffic graph. We added about 9k users in three days.

I'm writing up a technical blog post to go with the graphs, for people who are curious about what we did to keep the site up.

I signed up but I'm wondering, how does it make sense for you to run the site with just a small one-time fee?

The signup fee is there to put a brake on growth and offset the development and hardware costs of scaling the site when lots of new users arrive.

Our bread and butter is the $25/year from archival accounts.

Looking forward to that.
