Are you using Less CSS?

Hi, guys I run into this tutorial on the wp.tuts+ site http://wp.tutsplus.com/tutorials/using-less-css-blueprint-and-wp-for-a-faster-workflow/ and I am wondering if anyone is using this for their themes on TF? Are there any downsides?

well, i used the LESS for my project http://Tahadth.com and it made a problem with the 3g modem users, the style didn’t load, the page was totally ruined, so i had to precompile LESS to CSS and attach teh CSS it was a nightmare

I love LESS , but I don’t use the JS version for a live website…

I combine it with Less PHP , http://leafo.net/lessphp/ to precompile LESS to CSS file when I need it… I have no idea with Ruby…

My end buyers/customers will never see the LESS file…
