Typekit. I'm still researching web fonts and their simple use in various situations, especially the search for useful fonts. Typekit looks quite interesting in this regard, although their free offer is somewhat limited, the prices for the larger packages are not entirely utopian - at least if their claim of efficient delivery of the fonts via HTTP really stands up to reality. In principle, you rent the fonts for use instead of buying and hosting them yourself. There are a number of plugins for Wordpress, this one from OM4 also seems to be currently maintained.
