It's a simple design, but very clear. I went in with no idea what a website profile is, but when I got there, I got the gist of it very fast.

Looked up a few sites, the results were well-displayed and easy to understand. I love the little descriptions that come with each component.

Two questions - why sign up? I don't think it's made clear what benefits you get from creating an account.

Also, I don't understand the featured technology part. Is it a space for sites to get featured, or for technology, as in the stuff you use to make the sites?

Great that you like it. The signup is only necessary if you want to suggest or feature a technology, it will tell you this when you try to access these screens. The only reason the signup link is there is that if it wasn't there I'd probably get asked 'how do i sign up?'

The featured section is really for any technology related advertisements and is the $ part of the site.
 

Ahhhh.... Cool... thanks for clearing that up!

Featured content would be a great place for Tangler to have an advertisement for example or maybe rackspace.com etc..

Ah okay, so anyone could advertise... not just something like Apache for example? I got confused with the term 'technology'

ok maybe I should change that to make it a bit clearer thanks for the feedback

Pleasure

every site is using drupal, acording to this system 

yeah that was a bug that was very hastily fixed this morning

I just checked a couple of sites, and although it looks like it does the job, there are a few things I'd like to mention:

- my sites are not XHTML, but HTML strict. BuiltWith doesn't seem to be able to tell the difference

- although FrontPage extensions are an option on the server, they are not used on my sites, yet due to the title of the right hand column being "Site Information", not "Server Information", it looks like my sites do.

And a question: how can BuiltWith detect whether a site uses php or just static html? Does it have access to the document root somehow?

My suggestion is the ability to actual export the results to .csv or a pdf file for later referencing or displaying elsewhere.

Great idea for a site - much better than using Netcraft, etc. One thing though: our site (http://www.blueriver.com) shows up as using the .NET framework, but it's a ColdFusion site.

Any thoughts on what might be causing this?

Ruby On Rails detection is weak. Half the sites I checked were unknown.

BuiltWith claims that sites using HTML 4.01 Strict are using XHTML Strict. Not quite right, is it? And it doesn't even detect XHTML 1.1.

Thanks for all the great feedback, I will certainly get onto it. Nick: RoR detection is a bit difficult because normally nothing on the page identifies itself as using RoR unless the default session id key is being used or the server is using Mongrel. I am going to work on a stats part of the system where CSV, PDF export may be involved in that thanks and I'll fix up the XHTML/HTML references as well as the title for the right hand bar. Thanks once again!

CNN shows:

128.43% of all profiled sites use Cascading Style Sheets.

thanks. I removed that. I tried to do a site wide update of technology usage, but it failed half way through due to database size. The infrastructure started to crumble a bit

really nice - I was poking around trying to find out who is using the GWT. I noticed that you guys are using the YUI. I think you should say something snarky whenever someone points the service at builtwith.com 

Yes someone commented elsewhere about that it should say 'Commodore 64 and Hamsters' for builtwith.com

hehehehe That would be funny!

Gary, BuiltWith is a great idea cause most people think that a CMS is a ugly blog page... and the industry people sometimes think this way too...

We developed a local version that is becoming popular very slowly, cause people in our country have to see it to believe that this is a CMS website.

I've added a meta tag that we place on every site developed with our CMS software, but still don't see it in the results page of "BuiltWith.com"...
so, how long do you think that will it takes to appear in the results?? I've added the tag on last friday.

best regards.
 

Hi DarkBlueBA,

What CMS are you using? Maybe BuiltWith isn't tracking it. The pages are cached but deleted once in a while (today).

Our CMS product is "DarkBlueCMS", originally built to enrich SEO of our site...

Here, in Argentina people just get a graphic designer who takes care of all the site (design, code, etc) and the promotion of CMS products is associated with the ISPs "free sites", with just a few ugly templates... We know that is not fu#&@ true!! but it's a fu#@~% perception of the people that don't know about the possibilities of that kind of products..... we have to deal with that... =)

I see that our CMS is listed!!! thanks!!!
we'll use your site to show what we can do with CMS to our potential customers!!!
