No, you're not doing anything wrong. What you're seeing is the hex
representation of a BytesType, which is the comparator that Standard1 in
the example config uses. This is the same for 0.5.1 too.

If you haven't made any changes to the default config, try using
Standard2 as the column family and you'll see a human-readable column
name as expected (Standard2 uses a UTF8Type comparator).

The wiki page has sample output that is confusing, (it's probably
cut-and-paste from a time when Standard1 used an ASCII or UTF8
comparator), we should probably fix that.
