there is, I would suggest, a difference between complaints and whining.

Whining is only, really, allowed when you pay for a service. Other wise register your complaint calmly and sensibly.

Secondly there is a vast difference between losing some tweets and gmail losing emails or gdocs losing documents. Sure have a bit of a moan: but you can only really viably complain if what is lost has significant value (a point the blog writer makes whe nhe talks about grannies vs. companies losing email).
