Hi Greg,

Just looked quickly at your site, a few comments:

The link to the lttng website should be http://www.lttng.org rather than

Putting the distro name and version, kernel version, lttng version used
for the demo in the file name would be good.

If we see the need for it in the future, an x86_32 version might be
good. I fear a large quantity of users still run, at least their
userland, in 32-bits, so they will expect 32-bits userland packages.

You might want to add the file size beside the link, for informational

When we decide to announce it more widely, I think setting it up for
distribution with bittorrent might be appropriate.

I'll give it a spin in the next days and keep you informed,

Thanks for your contribution !
