"# Kdo podepsal výzvu vědců?\n", | |
"\n", | |
"V pondělí 17. srpna ráno byla do světa vypuštěna výzva vědců, která sbírala podpisy už od začátku července přes e-mail a uzavřenou událost na facebooku. Na [webu](http://vyzvavedcu.cz) tak už od onoho pondělního rána bylo 430 podpisů. Ten samý den večer už počítadlo podpisů ukazovalo přes tisíc a v době psaní těchto řádků se jejich počet blíží dvaceti osmi stovkám. \n", | |
