I believe that bolding and italicizing* text in posts is good, as long as they are used properly. My personal method of bolding and italicizing are below:

Acceptable uses for Bolding:

1. To create headers, like the one above.
2. To highlight easy-to-miss but important text in a block of text, like a long paragraph.
3. To emphasize content, primarily warnings and other cautions.
4. NOT to highlight specific instructions, such as "Run this command as root:"

Acceptable uses for Italicizing:

1. To highlight variables in code, like the example below.
2. To emphasize content, primarily warnings and other cautions.
3. To give special instructions to the user, ie (In the OPs case, run sudo -s instead of sudo -i)
4. NOT to highlight specific instructions, such as "Run this command as root:"
