I think that live blogging can be influential but it depends on what the topic is and it depends on how live blogging is being utilized. Music was used for the example; if someone was live blogging a concert or performance I wanted to go to, it would be their real life experience and it would be informative to me. If the atmosphere wasn’t fun or if the fans are rude and obnoxious, I would be able to know what someone live blogging about that. Likewise, if the artist wasn’t performing right or if they weren’t a good singer live, I would know. I think this is a pretty good summation of live blogging’s pros. The main point of live blogging is to show what is happening through your reactions. Live blogging at its core is informative. It may be colored with emotions or bias of a person but for the most part, you can somewhat tell what is going on. I think that live blogging something has the potential to change a perception but for the most part, it’s not really going to do anything. A smaller benefit would be that other people who are watching the same thing as you could point out something that you may have never seen otherwise. Many things from different events or movies have been pointed out in a live blog that, looking back, I wouldn’t have taken notice of.
As for the cons of live blogging, I think that spoilers is the main thing. If someone is a live blogging a show that you haven’t gotten the chance to watch or even if your tv is a few seconds slower than theirs, you’re going to get surprises ruined. The same can be said for the previous example used; if an artist has a surprise ending for their concert and someone is live blogging that experience, you’re going to go to the concert expecting it and it’s going to lose its effect. On the other hand, if someone live blogs about that surprise ending and then it’s not there for the concert that you attend, it may leave you feeling disappointed and cheated. I personally find that I can’t go on Tumblr at all if I plan on watching something later than its airing date. I’ve gotten spoilers for the Grammy’s, episodes of shows that have been out for about 2 days, the Presidential debate, etc. A very real and more serious con of live blogging is the potential to give information to the wrong people. In the event of a school shooting, if the school is on lockdown and there are people outside watching the police activity and live blogging the event, the shooter inside (who would most likely have internet access) could potentially look up the event and see where police are to avoid immediate confrontation. They could plan a getaway or a strategic shootout. More often than not, school shootings tend to be led by people who don’t actually care what happens to them. If they know that the police are in a certain area, they may just avoid the area and continue with their actions elsewhere (obviously this depends on the school). Regardless of what is decided, it’s never a good thing to alert the enemy of the positions that the police have taken or their activities.
