Its about time there is a search site that groks the web. Grok This
As in, "Hey Jim, take a minute and grok nanotubes."
Hopefully this will be added to our lexicon someday, along with tanstaafl and all those other Heinleinisms. Then again...
Grokker appears similar in concept to kartoo. And much faster.
Note: kartoo remains, while grokker is defunct.
