Just a little comment about your "plans and pricing" page: the double negative of a cross next to "no affiliate links" is a bit confusing at first.

I am used to ticks and crosses showing features that either are or are not present, in this case though there is a feature (even though its a negative one) "affiliate links" that is not not present. Kinda obscure.

Perhaps you could just have a smiley or frowning face next to each feature, that way you would see that the paid plans have more "good" things? eg: :) - tags! :) - filter by date :( - no tags when historifying :( - no rss :( - affiliate links

Or something to that effect.
