I've noticed recently that there has been a massive increase in the amount of BitcoinTalk account's being hacked.
See here for some examples:

Make sure you use a strong password (letters, numb3rs, $ymbols and upPeR CaSe LeTteRs).
Be careful when trading with people, the account may be hacked, look out for suspicious behaviour, use escrow when possible and do not trade with anyone who may be a risk.
It may be a good idea to add optional Google Authenticator 2FA. This would definitely help reduce the amount of hacked accounts.
