Google modifies site/page titles?

Some days ago I noticed something strange. The title of my main site is not
the same as that which the SERP's show. I am not listed in DMOZ, in case
that's a factor.

For some reason, my first name is appended to the <title>. For example if you
google 'site schestowitz' (or any phrase for that matter), the title will
show my name rather than the title. Odd... that does not even align with
anchor text. Could it be manually edited or part of a new algorithm?
