Great post you have here. To be honest, I have never created a roundup on any of my sites. But I do love to visit websites that constantly puts roundups on their posts. It surely is a great way to make your readers catch up on what you have created or posted in your site in a certain period of time. It is a very effective way to summarize things. Because of this, I am eager to start my very own roundup post to one of my sites. And with your guidelines, I feel confident that my first ever roundup will be effective and successful. Thanks for this very useful info. Cheers!
