What the student Liam Stacey tweeted was offensive and stupid, but given the great groundswell of support for Fabrice Muamba it was clearly out of step with the whole nation. So what was the purpose of the sentence (Student jailed over racist Muamba tweets, 28 March)? Stacey was clearly remorseful about what he did, so why take this issue out of proportion? The jails would be overflowing if all equally offensive comments resulted in a prison sentence.

• The suggestion (Letters, 29 March) that the "lady climber" in the photo published on 27 March is being pulled up cannot be substantiated. There is no evidence that she is even tied on to a rope. Her left foot sits in a loop tied in the rope, which she is pulling on with both hands. The shorts are most unusual for the era and the shoes, with a two-inch heel, look more South Audley Street than Cima Grande! Is this an early mountaineering pin-up?

• I now take it that since Royal Mail is allowed to increase postal charges and will soon be making a profit (Report, 28 March), there will be no need to sell it off to the private sector. The government keeps telling us it is so short of money; retaining Royal Mail would provide a form of steady income for the Treasury.

• Two Camerons plumbing the depths at the same time (PM's private lunches and dinners for Tory donors, 27 March; James Cameron's historic solo dive, 27 March). What are the chances of that?

• Is there anyone else out there who doesn't watch Mad Men feeling either marginalised or bullied (Just mad about them, G2, 22 March; Mad about the men, G2, 27 March; Didn't see Mad Men? Here's what to say…, G2, 28 March)?

• I wanted to add my local river to the conversation (Letters, 29 March), but was told to Beult up.
