W ostatnich postach<\/a> wiemy, \u017ce jedn\u0105 z metod zwi\u0119kszania wy\u015bwietle\u0144 strony jest pokazywanie listy post\u00f3w z przesz\u0142o\u015bci. Inn\u0105 metod\u0105 jest pokazywanie losowych post\u00f3w. Oczywi\u015bcie posty pokazujemy za pomoc\u0105 miniaturki w po\u015bcie, kt\u00f3ra b\u0119dzie przyci\u0105ga\u0107 wzrok.
