Topsy handles 301 redirects inconsistently (www vs. non-www)

[GoogleCodeExporter]

Topsy rightly considers www.domain.com and domain.com to be different sites, 
but definitely has a mechanism for knowing when one redirects to the other. I 
can't figure out a way to trigger it.

If you access http://otter.topsy.com/trackbacks.json?url=http://www.topsy.com/. 
The response begins with 
{"request":{"parameters":{"orig_url":"http://www.topsy.com/","redirected_url":"h
ttp://topsy.com/","url":"http://topsy.com/"}. I'm trying to achieve the same 
effect for my domain (borismus.com, formerly www.borismus.com).

What steps will reproduce the problem?

1. Visit http://otter.topsy.com/trackbacks.json?url=http://borismus.com/
2. Visit http://otter.topsy.com/trackbacks.json?url=http://www.borismus.com/
3. Note the difference.

What is the expected output? What do you see instead?

I'd expect topsy to notice the 301 redirect from my www to the non-www domain, 
and respond with a similar "redirected_url" response, effectively giving the 
same response for both requests in (1) and (2).

What version of the product are you using? On what operating system?

Using the currently live otter API (as of 2010-02-10).

Boris, next time the Topsy crawler visits your pages, it'll note the redirect.  
One way to force it is by posting a link on Twitter that has not been posted to 
Twitter before.

I tweeted a previously untweeted url: http://www.borismus.com/moving-day/ and 
now I get the correct redirected_url business in the response for that and 
http://www.borismus.com/.

Still, nothing seems to have changed for
http://otter.topsy.com/trackbacks.json?url=http://www.borismus.com/android-phone
gap-plugins/ vs
http://otter.topsy.com/trackbacks.json?url=http://borismus.com/android-phonegap-
plugins/

Any ideas?
