I haven't found a duplicate, though it seems to happen for all migrated questions.

This question has just been migrated from SO to SU, and doesn't show its author in the "recent questions" page.

I guess it's because there is no "last activity" recorded on SU, but the timestamp still shows, so I guess the author should as well. Especially that this user has an account on SU as well.

Not really a blocking thing, but just reporting it.

Some background on why this happened.

On the home page and certain question listing pages, we display the user and timestamp of the last activity on questions.

Last activity is primarily * any asking, answering, or editing that happens on a question or its answers. When activity occurs, we update two fields on the question record:

LastActivityDate (datetime, null)
LastActivityUserId (FK, int, null)

The issue you reported showed up because, at the time of migration, the question owner did not exist on SU. After seeing the question was migrated, the owner created his SU account and then associated to SO; question ownership was also resolved during account association.

What was not done was setting the LastActivityUserId during the account association process - we can fix that, but most users with migrated questions aren't as diligent as Uwe in creating new site accounts to tend their migrated questions. So this issue will still persist most of the time.

Thank you for reporting it, though - we can still make migration/association a little bit better :)

* starting a bounty also updates last activity

The small fix will be pushed to all sites tonight. –  Jarrod Dixon Apr 26 '10 at 14:38
    
Thank you for the detailed explanation (and fast part of fix). –  Gnoupi Apr 26 '10 at 15:09
    
I just found another one a few minutes ago. Shows fine in the complete list, but is missing the author on the home page. Does this imply that "the small fix" didn't work? If I recall correctly, then Community used to be shown for the last activity? –  Arjan May 16 '10 at 9:32
    
And, @Jarrod, do you think missing authors in the revision history might be related as well? This migrated history shows no name, while the author (who answered at Stack Overflow) is actually also known at Super User, and shows fine below the answer itself. –  Arjan May 16 '10 at 21:15
    
Noticed this behavior still occurring. Is there any plan to update it? –  Farray Sep 22 '11 at 17:25
