Dear CSS framework writers (not just Neat) can you start adding a section to your docs that states what Browsers your frameworks are supposed to support. This doesn't work in IE8 at all, which is fine if your not going to support it as long as you make that clear.
Zurb Foundation (<a href="http://foundation.zurb.com/" rel="nofollow">http://foundation.zurb.com/</a>) is another great one that's done with Sass.<p>I tend to prefer it over the more intrusive styles Bootstrap seems to add; Foundation lets you more easily pick and choose what you do and don't want to drag in.
What I do to avoid the class soup Bootstrap expects you to use in your HTML is import bootstrap.css in LESS/SASS and then inherit its classes in my semantic classes. E.g.,<p><pre><code> .userprofile {
.well;
}</code></pre>
Susy (<a href="http://susy.oddbird.net" rel="nofollow">http://susy.oddbird.net</a>) is another well-designed option for semantic grids that's been around for awhile.

Definitely nice if all you want is the flexible grid system from something like Bootstrap. Sometimes it can be a pain attempting to only use a certain component, and for something as core as a grid system, this is most certainly the lightest method.
