I am a one-brainer, that is I only have one Personal Brain. After four months of use, I already have 6.200 thoughts and 8.800 Links, and the associated _brain\brain_cdbb\THOUGHTS.tbl and LINKS.tbl files have a combined size of 200 MB.
How big is YOUR brain? Who has got the biggest brain, and how big are your .tbl-files?
Let us make an enquête!
