I like finding and reporting bugs. It helps to make products better. And it is a good source of learning.
Over time it has become such a big number of bug reports that I'm writing, that I finally decided to keep track of all the bugs in lists.
Please note that these lists are definitely not for discrediting certain products. The opposite is the case. I will only ever report bugs for products that I believe in, and only to organizations and companies that I believe will take bug reports seriously. It should never be forgotten, that there is no such thing as perfect software. And finally, quite often my bug reports refer to beta software which is explicitely released under premises like "known to have bugs".
