OK, I probably needed to give that a bit of a rational.
It would be nice to have a blog for a bit of editorial content on the ASLO.
Many app stores have things like featured apps of the week and stuff and it
would be nice to have that - I could help write some.
It would be impossible to make it work for every sugar user (every lang...)
but it would be nice for some users.

Thanks for the tips :)
I have taken tried out many of them; and there has been noticeable
improvements in speed (~311kb vs ~700kb).

I also got a (free) domain (freenom is a good site :P) and tried out
cloudflare.  Try it out at http://aslo.cf/
They have some pretty evil js compression which made it a lot faster - but
since it broke some sloppy code I had to disable it - I will fix that so I
can get REAL FAST JS!!!!!!
Otherwise the performance is pretty similar (I think the biggest thing
cloudflare does is merge js files automatically - which I am doing already).
Supposedly clouldflare takes load off your server; I am waiting for my
dashboard to update for stats though :)

I will look for some metrics, but maybe clouldflare could help take some of
the load for the current aslo (17s load according to firefox) and
www.sugarlabs.org (100% static = 100% cache-able)

OK, I will start writing a login system.
I will try and make it integrate really well with sugar (read: lets hack
browse activity to have 0-click logins).

OMG. I see in firefox that about half of that time is DNS! It is on
sugarlabs servers so maybe our dns is really bad!  I have no idea about
this, maybe @Bernie will know?

OK, you know a lot more about this that me; what do you recommend?

Ok, I'll fix it......... soon........ -ish.
