I think it's probably a consequence of the freeze - essentially, there are no
changes to the (former) Testing distribution. Testing stops accepting packages
as the freeze happens. If you have it tagged by codename, you get minimal 
changes
other than bugfixes at the moment in the run up to the release of Squeeze as 
stable.

This is another argument for using the code name of a release as your mechanism
for updates in /etc/apt/sources.list. [See below]

Sid is always unstable - never released - the backronym is "Still In 
Development"
Don't run sid unless you are prepared to deal with a high pace of change,
a high churn rate in terms of packages and a degree of breakage. 

If you do run sid, be prepared to follow some of the developer lists within 
Debian. If, for example, there's a new, incompatible release of GNOME/KDE/GCC
- KDE 3.5 -> 4.x, Gnome 2.x -> 3.x, GCC 4.x -> 5.x - then there will be huge 
change
which may take months to work through in stages and involve several thousand 
packages.
Smaller library changes may break swathes of apps, sound system changes
may involve fixes right across the board, major changes may occur as
we move kernel versions as whole subsystems break and are fixed. If you know, 
for example,
that a major change to KDE is coming, you can be prepared for a couple of 
months of large
numbers of changes on a daily basis. Could be a few GB a day on a bad day :)

Testing looks like  a "bathtub curve" - lots of changes at the beginning which 
were waiting to be
made as the freeze occurred, a fairly constant flow through the progress 
towards a freeze, and a huge
number of changes/bug fixes at the end as they're knocked out in order that 
it's released as stable. 
There will be lumps - as groups of packages come in from Sid - but they're 
likely to be less noticeable.

Once a release is stable, there will be security updates, there will be point 
releases which round these up
but there's no change. Once release+1 happens, that release may become 
oldstable and be supported for up to
a year.

Unstable                        Testing                 Stable                  
Oldstable

Sid                             Lenny                   Etch [4.0]              
[Sarge]
Sid                             Squeeze [6.0]           Lenny [5.0]             
Etch [4.0]
Sid                             ??? [7.0]               Squeeze [6.0]           
Lenny [5.0]
Sid                             ???? [8.0]              ???? [7.0]              
Squeeze [6.0]

Typically, releases take two years, and oldstable's there for a year or so, so 
you get three years. 
Exceptionally, if you'd had a Lenny system tagged as 

# 

deb http://ftp.uk.debian.org/debian/ lenny main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ lenny main contrib non-free

deb http://security.debian.org/ lenny/updates main contrib non-free
deb-src http://security.debian.org/ lenny/updates main contrib non-free

deb http://volatile.debian.org/debian-volatile lenny/volatile main contrib 
non-free
deb-src http://volatile.debian.org/debian-volatile lenny/volatile main contrib 
non-free

at the day you first knew the codename for the next release, then you'd have 
had five years support with no changes needed.

Otherwise, if you tag by unstable/testing/stable you end up with a flag day 
whenever "stable" is released

My lenny machine will age gracefully with no apparent change as stable -> 
oldstable - but I've then got about a year
to get round to upgrading it :)

Hope this helps,
