It’s a rich, rich source of information and interaction. But it’s doing my head in. That’s why Jim Hendler’s blog post last Friday hit home so well. His piece is about finding the time to blog, which itself is an issue for me. But if I add to that the distraction of Twitter, the problem is compounded. I keep thinking back to Richard Hamming’s remarks about sustaining that 10% extra effort in your science so as to reap long-term benefits in progress and productivity. And I wonder if blogging and twittering has soaked up that time from my schedule. I think it might have.
