Yes, front page shows you the "hottest" things based on https://www.drupal.org/project/radioactivity then all of the content can be seen (using the same sort criteria) by clicking the View All button at the bottom of the listing. Radioactivity is surrogate for the popularity of a posting but we need to review the rules to see if it's good enough and tracking "views" is not necessary. Tracking views is tricky since you have to do it by user (if logged in) or IP (which may not be reliable) and with the caching you have another issue.

Do you think that the number of postings on the home page is correct or should we change it? As I mentioned above new filtering is coming plus a better way to manage the content by tag.

The items there are not random. Sorted by radioactvity_value, last comment date, post date all DESC. Header took up too much space and had to go. Announcements can be set in a way that they show up in the right column as Top Stories. It's free of filtering by group or tag, you can do that elsewhere on the site. Ratings needs to be completely reworked so it's not currently factoring into the sort, nor is the number of comments. This somewhat cleaner display is making way for new filtering coming in a week or so which will have "My Content", "Most Active", "Highest Rated" and "Unanswered". Tag filering will also be revisited (eventually).

Content rating is going to get completely reworked, most likely to the +1/-1 system. Any change to the current rating scheme was unintentional. We'll be doing releases each week for the next few weeks and rating changes will likely be in the release two weeks from now. Next two releases will focus on the following:

- more UI layout and usability enhancements

- improvements to authoring / editing

- new content types (articles vs. generic postings)

- internal tools for porting content from other systems

- new content filtering options

Tagging will be improved in a number of ways including driving ALL of the content using it and away from the "discussion group" style of display. Getting this all functional so that documentation is also granular enough and tagged in an efficient manner will take some time.

Not so sure about the crowd-sourcing method and/or being smart about suggesting tags. We need to build up a body of content and participation to get that functioning well, so it may be more suitable in the long term once we get some network effect going. It would be interesting to apply some AI to make tag suggestions.

We will at least have a "browse by tag" functionality but it's uncertain if this will just be a simple list vs. the "cloud" style of display.
