When posting a question on StackOverflow, people can tag their posts as iText or iTextSharp questions. This allows me to quickly find those questions by performing a simple query for posts tagged as itext* questions. This includes the tags itext, itextsharp, itextpdf and itextg.
However, not all questions tagged this way are iText-related. Sometimes, people using iText have questions that are about PDF in general.
