During the design phase, the product manager and the developers categorize the requirements as (a) Must have (b) Nice to have.
During extensive testing and often much later, bugs (of varying severity) show up. Some subtle errors are dubbed “features”.
Facebook has a couple of features.
In group photos with Yours Truly, FB would tag me as my brother. The error might be due to the
- facial recognition system (which is not yet perfect)
- unintentional tagging (by some user hitting the wrong key when asked to tag)
- the guesstimate (“guess estimate”) algorithm to “match” faces and names (in the post)
I would often get friend requests from some questionable FB users.
- There are several who belong to 50+ (or 100+) groups. I am not sure whether they are humans with lots of free time, or robots.
- The meaning of a friend (e.g. A friend in need is a friend indeed) has been “downgraded”.
- Some have no photos and bare info on their timeline.
The “View As” feature contributed to an opportunity for data miners, hackers and crackers.
