Richard Baxter (1615-1691) was an English Puritan leader and scholar. Dean Stanley of Westminster called him "the chief of English Puritan Schoolmen."
Among many other excellent treatises, Baxter wrote an "Advice on Reading," in which, he provided four questions to ask yourself while you are reading:

1. Could I spend this time no better?
2. Are there better books that would edify me more?
3. Are the lovers of such a book as this the greatest lovers of the Book of God and of a holy life?
4. Does this book increase my love to the Word of God, kill my sin, and prepare me for the life to come?

Excellent and challenging advice. Applicable to many areas (music, television, movies, video games, etc.) But consider this, if Baxter gave this advice to your reading, would the same advice not also apply to your writing?
When you are writing your post, ask yourself if you could not be spending your time better. Could your post be more edifying? Could it be made more valuable to the reader? Is your goal to be popular? Or to hold high the Word of God? Will this post help other live a life of godliness? Or will it distract from God or raise unnecessary skepticisms?
I have certainly been challenged in my own blogging.
