The search index, ratings and reputations are now pinned to memory. This should reduce delays in searches and page loads.

Adding a link now uses the search index to check if the link already exist. This should fix the extension popup loading for a long time.

Per-account reputation count is now capped to 20k. Reputations closest to 0 are discarded first. This should speed up viewing suggestions.

Search now requires an exact match. Wildcards coming later.

Updated guide to explain how to add a friend, how to create posts and feeds.

Exclusive terms now work with a minus sign. Add "-thing" to your search to remove all items with "thing" in the title. This is now also explained in the guide.

Changed the pricing of bronze and gold plans. Added platinum and diamond plans for power users.

Optimized search. Text search no longer finds itself as a search item.

Reputation algorithm recurses now only into searches rated by the user.

Added icons to all account, feed, post and search items.

Optimized text search and suggestion search.

Post and feed creation panels are now in the profile page. Adding links works still through the search.

Many small tweaks and fixes.

Completely changed how collecting works. Topics are now Feeds. Users can collect items only into their own feeds. No longer do blue items (objective feeds) have subjective contents. This change makes the system simpler, better and more scalable.
