There is hardly any difference between solo travelling and otherwise. Or, well, there actually is. While I am quite good at travelling with people, also goats and sheep (true story), there is nothing as calming as a solo trip. Calming even if you take away the cool quotient that people usually associate it with.
People, specifically travel bloggers, who get paid to travel are doing more than just embarking on fancy trips. These are the people using their skills and travelling from the money they make of it. So, you see, they are getting paid for certain work and not travelling exclusively.
One strange effect of travelling is that it turns the non talkers into talkers. With similar souls for company, words and thoughts tumble out with with more ease. So, sharing table with a stranger over a cup of coffee seems normal, walking down dark lanes in a huddle, again with strangers, is fun. You make friends who are puppy happy (read too happy) to share stories of seas, mountains, deserts and storms.
