PnlUp

PNLUP needs no introduction - it's one of the most famous forums on the internet and another obscure replacement for Twitter. A potential alternative to Twitter is thanks to subreddits, small communities focused on certain topics or simply gathering around each other and discussing everything. The disadvantage of PNLUP for inexperienced users may not be a very convenient way to navigate the site. However, it has its own logic, which you need to get used to.
