Although it may not seem like it, the last couple days have been busy for Yim and I. After we implemented search by city, we later realized that clicking on next page would point you to all results. Quite annoying...
Well, we fixed it this past weekend and things really blew up. Apparently the blind search stopped working which slowed down our sign-ups dramatically (as well as overall system activity).
We finally have all the problems licked (and yes, if we only ran our unit tests before deploying these fixes we would have caught them).
On the architecture side, we've finally moved up to rails 1.2 and made some configuration changes with our e-mail delivery. We've done our best to make sure e-mails still work and the site in general is stable.
In the next couple of days, we'll be making some more changes to our e-mail infrastructure. We're planning to integrate the Plaxo Address Book API for our invitations, so that users can finally perform so-called "mass invites."
As part of our sign-up process, we'll also begin asking users to spread the word. In the early days, we used to prompt people to invite friends - but back in those days, we had less than 100 people and we were told it was presumptuous. Once we've rolled out these changes, both new users and existing users can invite their friends that are already in the address books of their gmail, yahoo, msn, or outlook clients.
We're hoping this will help generate more word of mouth so that eventually we can stop advertising on search engines altogether.
Because of all of these changes, we're really leaning on the user community to inform us if they see any problems with the site.
Please let us know if you see issues, and happy stumbling!
