Hello;

When make the change (and the #94 ) tweet text is not insert in the database, the 'text' table is empty.

Have you make other change ?

[golddave]

These changes have been working fine for me with no problems. What if you keep lines 90, 105, 126 168 and 169 of this pull request (only change line 16)? Does that work?

Yes. Makes sens. It's works. Thank you.
