Consider having a church blog if:
Some churches have Pastor's blogs (with postings about current church events, sermon thoughts, world news, local happenings, etc). This can help those both in and outside the church understand the church leader better. Some Christians keep blogs about 'life as a Christian' etc and these can be very powerful evangelistic tools.
Not only can the authorised person make posts on the blog but also they can permit others to write comments on the posts. You could encourage your youth workers to run blogs that the youth can interact with: helping build community.
Over time the blog will grow and it will automatically archive previous posts providing a historical view in to the mind and life of the author. Most blogs archive in a reverse chronological order so you can see this month's postings, last month's postings etc.
The trouble with blogs is that worldwide there are many people writing blogs that barely get read. Before embarking on a church blog consider who you are targetting it at and what the likely response will be.
A blog can almost certainly work alongside your existing church website (church123 is compatible with all the major blogs).
A church blog can be setup for free with many reputable providers. Be careful of unknown providers as if they close down you may lose all your blog history (previous posts you may have made, potentially over a number of years!)
