Unlike Robert, I appreciated the length of the letter.
If you want to explain something clearly, you need to use the right amount of words. Too few, and you end up with bullet points that don't deal completely enough with readers' concerns.
All of Robert's questions would have been answered had he finished reading the letter, which, though long, was not too long. (If he thought the letter was too wordy, I wonder what he must think of BPL magazine, which has far more words.)
If anything, I'd like to see even more words in the magazine, though not at the expense of photos or other graphics. I think this can be done fairly easily.
For example, in the 18-page interview with Isaac Wilson (Issue 3), the questions and answers are greatly and unnecessarily indented, resulting in one-eighth of the text space going to waste--the equivalent of two full pages over the length of the article. I recommend modifying the format: Leave the questions and answers full-width, but include a blank space just above them.
Similar modifications could be made elsewhere. Page 16 of that issue shows one possibility. Half of the page consists of a bulleted and indented section of text. In fact, the text is doubly indented, as compared with the standard indentation of the first line of paragraphs. It would be enough to indent these paragraphs singly, either without bullet points or with bullet points that are placed at the left margin.
I know these are small matters of layout, but, if taken cumulatively and consistently, they would mean as much as five percent more text in an issue, with no diminishment of the graphics. Aside from Robert, perhaps, I think all of the readers would like more words rather than fewer.
