Facebook is introducing hashtags, the number signs
used on Twitter, Instagram and other services to identify topics being discussed and allow users to search for them.
For example, number 1 is the number sign
plus the letter "a," number 23 would be the number sign
plus the letters "b" and "c" and number 734 would be the number sign
plus the letters "g, c and d" [ILLUSTRATION FOR ILLUSTRATION 2 OMITTED].
If a large number sign
up for full-day classes, one bus route could be eliminated, but it is too early to say for sure without definitive enrollment numbers, Kane said.
