Excellent related post plugin! Developer friendly.

Excellent related post plugin! Spend a couple of days finding a good one, and many are either missing relevant features, no longer updated or way to bloated. Related Posts by Taxonomy simply nailed it, working fantastic out of the box, outputs perfect valid code and with its well documented selectors its a breeze to style to your likening. Took me 10 minutes and 4 lines of CSS and I had related and relevant posts in my blog post footer exactly like I wanted it.


Concise & flexible

Does exactly what you need, and the default options provide a good selection of related articles, which can easily be customised further.

Very good

Works very well and developer provides top-notch support! Helped me troubleshoot a style issue and went ahead in providing a CSS fix specific for my theme. 🙂
