I think you can rely on the courts, the prosecutor and defense counsel to handle any influence on a potential jury. There are several methods of handling this issue. One is voir dire where each side, prosecution and defense, have a certain number of peremptory challenges. Depending on the charges, the statutes define the number of peremptory challenges for each side. Second, the courts have a number of means of handling juror misconduct for bringing into the jury room evidence not presented at trial. They generally have a number of substitute jurors who sit through the whole trial and once deliberations start, if there is reported jury misconduct, the judge can disqualify the juror and plug in a substitute. Third, they can make motions for a change of venue. Believe it or not, not everyone in the US who is qualified to be a juror is following the blogs. Below are some Florida statues. I haven't updated them.

(10) The juror has a state of mind regarding the defendant, the case, the person alleged to have been injured by the offense charged, or the person on whose complaint the prosecution was instituted that will prevent the juror from acting with impartiality, but the formation of an opinion or impression regarding the guilt or innocence of the defendant shall not be a sufficient ground for challenge to a juror if he or she declares and the court determines that he or she can render an impartial verdict according to the evidence;
