I am one of the ask users who came over. I have never heard of Sodahead. If that helps answer or not, remains to be seen.
Is it coincidental that Askers and Sodaheads have arrived here at the same time? Were both sites owned by the same company?
We sodaheaders got booted off on the first of this month (about 2 weeks ago) with no warning. I just discovered this site a few days ago while hunting for a new replacement and so far I like what i see (and I will spread it around). However. I was never part of Ask.com but I saw the colsoure message and it was impressive that the owners of Ask had the decency to give a few weeks notice to their users.
We SH's had no time to give out contact info to our friends or to save old messages from people who have passed away etc..
