I run a Usability/UX blog, and my biggest hurdle right now is finding examples to illustrate the topics I write about (bad error messages, good implementation of tabs, bad interactions...etc)

So is there a website that has, for example, a database of categorized/tagged interface screenshots from various web sites on the web?

    Not an answer, so I will just put it as a comment. I haven't seen something like you are describing. I blog about UX frequently, so I know what you mean. commadot.com – Glen Lipka Jan 29 '10 at 17:32

These are the pattern repositories I find myself referring to most often:

It's also worth having a look at various operating system interface guidelines for inspiration:

Finally, if you're looking for some good books on the subject, the O'Reilly "Designing Interfaces" series is a great collection of pattern libraries:

There quite a few more design pattern resources out there, but these are the resources that I've found to be the most useful.

  • Thank you very much, I voted for your reply since it's very useful, but it's not really what I'm looking for. The design pattern was just an example. I've modified the original post to make it clearer now. – Mashhoor Jan 30 '10 at 17:16

You asked for examples of good and bad web elements of various kinds.

Here are some resources from which you can draw examples, screenshots, ideas of sites to look at, etc., on which to make ux-specific commentary:

    Thanks Nathalie! although this isn't exactly what I'm looking for, but it will be a great resource for me to build my own collection of screenshots and ideas. – Mashhoor Jan 30 '10 at 21:50

I'm sure there are plenty more, but my favorite resource for this type of data is Pattern Tap.

  • Thanks! that looks pretty nice, too bad their search capability is weak though. :( – Mashhoor Jan 29 '10 at 22:36

    Thanks for the link, but what I'm looking for isn't limited to design patterns only. I also look for things like "bad error messages", "tedious sign up form"...etc – Mashhoor Jan 29 '10 at 22:37
