Or more appropriately - nothing to do with art.
Every now and then I find a new online tool that changes my life, in a large or subtle way. Getting a feed reader was one of those moments (and yes, I've tried to convert you before). It's completely revolutionised the way I engage with news, ideas and people online.
A subtle improvement: when I found out that in Firefox (and if you're not using Firefox, what kind of art-loving liberal are you?) clicking on a hyperlink using the scroll button on your mouse forces the page to open in a new tab.
My newest find is Google Notebook. If you do a lot of research on the net, copying and pasting chunks of text and URLs into Word docs for later reference, this will change your researching life. It's simple, lightweight, and being an online application you can access it anywhere - fantastic if, like me, you work from two different computers. [If you just want to save interesting web pages but your Favourites are overflowing, I recommend Ma.gnolia].
