Lately there has been some discussion about the number of posts (and their quality) on Planet Drupal.

Personally I don't think Planet Drupal is hard to follow because of the large number of posts. There are plenty of other high profile planets with far more posts per day.

Let's compare:

Planet
Posts per day
Feeds aggregated
Mozilla
18.2
234
Ubuntu
17.5
271
Apache
15.9
160
GNOME
14.1
254
Drupal
12.5
261
Android
7.6
21
PHP
6.6
97
Eclipse
6.3
169

Note: The number of posts per day is based on the Subscription trends for the last 30 days of my Google Reader.

The question whether all posts on Planet Drupal are on-topic is harder to answer but in my opinion Planet Drupal is doing just fine. I would say that at least 95% of all posts are Drupal-related. People familiar with Planet Apache will confirm that you have to look really hard to find any posts about Apache software among all those holiday pictures.

It is probably true that not all posts on Planet Drupal have the same high quality writing - I'm not even convinced that this posts has - but that is all part of the mission of Planet Drupal: "Planet Drupal aggregates broadly appealing, Drupal-related blog posts pertaining to the community at large (code, advocacy, marketing, infrastructure etc.)".

In the end, it is really easy to skip a post in your favorite feed reader, isn't it?

PS: I think it is far more annoying that the feed of Planet Drupal contains only teasers instead of full posts. Whenever something really interesting appears I have to click to read the full post. Most other planets only accept feeds with full posts.
