Aerogel: Has anyone fooled around with this much ?

a Link to a recent Aerogel article

Anyone mess around with this stuff at all? Is it still a bit on the steep side price-wise ?

As a Building material

Notice in the picture how well it insulates against a torch flame:

Bumping an old posting to include a relevant link:
Ha, I just popped over to post this:

How to make aerogel.

Interesting. The MAKE article links to "cat=10", which ends up the same as your "cat=41" URL.
There are many ways to skin a cat.

Some ways could end up "cat-a-strofic" however.

Marketech will sell you smaller pieces for about $15/gram (minimum size 10g for $135), and a nice 4x8 inch slab for about a grand. There are some other sources listed on Hubert's Aerogel page.
Some of the 1+F supercapacitors claim to be based on carbon aerogels...
I've always been a bit disappointed that you can't seem to make an "amost aerogel" in a home lab - after all, you can make a water-filled silica "gel" by mixing acid and waterglass; in theory all you need to do is remove the water without letting surface tension destroy the silica structure. In practice, though, it is pretty hard...
There seems to be an increasing supply of aerogel in coarse granular form (probably MUCH easier to make, but not as neat.)
And trebuchet03 is right; fumed silica is sorta the same stuff. But it's barely solid...
