When it comes to the weekly bulletin or posting some news on the church’s website, the content is the most important thing. But we must also think and consider the layout of the prose and type so that the message is communicated in as effective way as possible.
Taking time to improve the typographical elements such as apostrophes, dashes and quotation marks is important as it shows a level of detail and effort has been put in. It demonstrates that the church is interested in the small details as well as the ‘big picture’. And it just looks better, even if the reader cannot identify why.
There are many resources on typography, but a key reference for the web is the alistapart.com typographical design archives. For a recent summary see the ‘Web Typography Sucks’ lecture notes from the recent South by South West conference.
