I chose a week time frame for many of my questions. Can I send
clarifications for answers after the 1 week? What exactly happens at
the end of the week? What ends and what is still available? Can I
request a certain researcher? I would appreciate it if you could
beyond my questions and answer any of the other questions that you've
heard over and over about this service. I'll put a $ 75 price on this
so that I can get a in-depth answer without having to go and research
the site myself.

Thank You,
Joel

Hello Joel1357-ga,

Thank you for this question and for all your questions to Google
Answers.

For future reference, we recommend that you send all your questions
about Google Answers to:

answers-support@google.com.

This way you will get the fastest, most thorough answers to
Google-Answers-related questions - and the answers will be free. 
Essentially, we like to keep the Google Answers site focused on
providing answers to 'real' questions from our customers and not
focused on questions about 'us'.


In brief answer to your questions above:

After a question EXPIRES, an asker can still post an answer
clarification, and responses to answer clarifications can also be
posted.  Comments can also still be posted.  But, a new, original
answer can no longer be posted after the question is expired, nor can
a question clarification be posted by a researcher.

If a question is CANCELLED by the asker, something different happens. 
Then no further activity whatsoever can be posted to a question - no
comments, no clarifications of either the question or the answer, and,
obviously, no answers.

Right now, there is no way to formally request a specific researcher
to work on a question on Google Answers.  By browsing the site, you
can see that some askers are attempting to draw the attention of a
specific researcher to their question, with varied success.  Sometimes
other researchers on the site will honor the request, and sometimes
not.

Finally, there are many, many questions we receive about the service. 
They are too numerous to list and answer here.  For more information
and answers to frequent questions, please read the Google Answers FAQ
at:

We hope this helps.  If there is anything that is not clear in this
answer, please request an answer clarification or email us at
answers-support@google.com.

Thank you again for using Google Answers!  

The Google Answers Team

Thanks

You state that, "After a question EXPIRES, an asker can still post an
answer
clarification, and responses to answer clarifications can also be
posted.  Comments can also still be posted." In my experience, this
isn't true. Here are links to expired questions on which no comment
buttons appear:

https://answers.google.com/answers/main?cmd=threadview&id=31203

https://answers.google.com/answers/main?cmd=threadview&id=34309

https://answers.google.com/answers/main?cmd=threadview&id=33949

It seems that unless someone posted an answer or comment before the
expiration date, we can't add comments after the question has expired.
Is this intentional?

Well a question of mine which I had forgotten about having written
months ago had a comment added by someone only a litle nwhile back
quite unexpectadly and when i would have thought that any addition
would have been impossible because access would have/should have
expired by now; but apparently not
