Boost your user engagement!
Votely is simple opinion system that acts as a poll, which is placed at the end of each post once added during post creation (check screenshots). Its perfect to gain user attention and increase engagement. It should be used for simple opinion questions with Yes/No answers, anything lengthy will decrease engagement, thats why for now you can only add 2 answers. It comes with twitter/facebook share which allows sharing of poll on social networks easily, its also responsive.
Votely is fast, ajax powered, coded with best practice, super light and will not slow down your site.It has one script and one style file that is loaded only on post that has votely activated!

I love the 'end-user'! Everything we do on the web is always about the end-user. And this fella really "gets it".  I browse org/plugins/browse/new/ for a few minutes each night before I sign off. Every one of his plugins - I look at and think, "I can't think of a site that I wouldn't use this on."
Every one of his plugins!
And, yet.... He did it again!!
