Ecco il mio bookmarklet per tutti i siti Stack Exchange:
Questo codice mostra il conteggio dei voti positivi per tutti i tag che compaiono nella sezione dei tag principali della tua pagina utente. Dovrebbe funzionare su qualsiasi sito Stack Exchange a cui si è effettuato l'accesso (ma l'ho provato solo su Stack Overflow e Meta Stack Overflow). Sfortunatamente esiste un bug nella logica di reindirizzamento dei sinonimi dei tag che impedirà a questo script di funzionare con i sinonimi dei tag.
