Fine next version(v3.0 codename "Amazing Anteater"(will release approximately next week(with many new features and refactored code))) will have a /Some_Word_filtered/gim regexp filter, so you will enjoy spending next few years building it from scratch.
The filter is just a quick way to remove posts i find useless to concentrate on the post i find more interesting.
example: 30 posts about superiority/inferiority/problems of lisp/scheme/haskell/Language-I-Never-Use vs single post about some topic which isn't in the filter. If i find the post useless i can add to the filter, so my next time browsing i'll will skip it too, exponentially reducing the stream of useless(to me) information. I never said you HAVE TO USE MY FILTER, just copypaste any filter you like from any file you like.
