Steve Rubel has written a Ten Blogging Hacks post.
There are some interesting suggestions there like using Writely as your blog editor (I have written about Writely before) – Writely has a spell checker and allows for online collaboration in writing so if you want to collaborate in the drafting of a post, Writely could be a useful blog editor for you. One disadvantage for me is that I use a WordPress plugin called Ultimate Tag Warrior to add Technorati Tags to my posts – this functionality is unavailable within Writely.
Some of the suggestions are a bit trivial – like the “Blog from your cell phone” suggestion – how often do you need to do that?
Still the list is well worth checking out as at least one or two of the suggestions are likely to appeal to you.
