Frank Meeuwsen asks Show me your blogroll considering them "the best artifacts of the Early World Wide Web". They certainly help with discovery of other bloggers.
I had a dedicated blogroll for a while on the old WordPress site but also a 'pseudo-blogroll' (called The Directory) automatically generated from those who sent me webmentions. The Directory was a different approach that allowed people to discover other IndieWeb bloggers.
I no longer have an explicit blogroll but my /reader essentially performs the same function and has an OPML file available for download. The OPML is automatically updated whenever I add/remove a feed to/from /reader.
As I always say, what better recommendation can you make than the feeds you actively read yourself.
