Note that Twitter returns 0, 1, 'true', or 'false' for these fields:

• 'protected'
• 'verified'
• 'geo_enabled'
• 'contributors_enabled'
• 'status_truncated'
• 'status_favorited'

You must convert any 'true' or 'false' string returned from Twitter to 1, or 0 before saving to this table's tinyint(1) fields.

MySQL varchar lengths are calculated by multiplying the max length Twitter allows for the field * 4 to allow for potential 4 byte characters.

• name = 20 * 4 = 80
• location = 30 * 4 = 120
• description = 160 * 4 = 640
• url = 100 (This is Twitter's max length and only 1 byte characters are allowed in URLs)
• status_text = 140 * 4 = 560

However, running max(length(FIELD_NAME)) on Friend Or Follow returns the following:

• location = 370

language should allow for 'en-gb' so CHAR(6) seems more appropriate

twitter does not do en-gb just en
