Those who are serious about effectively reaching the lost take to heart the Scripture "it pleased God by the foolishness of preaching to save them that believe" (1 Corinthians 1:21, italics added). When a love-motivated Christian has the courage to stand up and preach open air, he or she is imitating Jesus, whose ministry was mainly to the multitudes in the open air. This was also the way of Peter, of Paul, and Stephen and many others in history such as Spurgeon, Wesley and Whitefield, who cared enough about the lost to look foolish in the eyes of a proud and sinful world (see also Titus 1:3). Armchair critics, who say that it's not effective, denigrate the very means that God has chosen to save those who believe. The Christian who obeys the Great Commission--to "preach" the gospel to every creature, trusts God in both the means, and for the results of preaching the everlasting Gospel. God's Word cannot return void. Their labor is not in vain.
