Blogging is mostly a pastime for yours truly. It does render a service that is of some value to others. Our small but loyal readership (around 5,000 each month) seems to prove that. But is it useful? Not in any direct, day-to-day-life kind if way, I don't think.
However, others are able to blog a post that is of direct significance to us, in this summertime. Mario Vittone is one such blogger. His post Drowning Doesn’t Look Like Drowning should be read by any parent and all who venture seaside in these hot, sunny days.
Whoever said blogging has no use?
