Read the ciphertext. Strip whitespace: 3,856 hex characters = 1,928 bytes = 241 8-byte 3DES blocks.
Derive the key. Password = A858DE45F56D9BC9201301051959 (name+title). Key = MD5(password) = 16058b3237fcb01a07c127dbf06c5f5c, used as a two-key 3DES key.
Decrypt. 3DES-EDE2 in ECB mode, then strip the PKCS7 padding. The plaintext is 60 GUIDs as hex (shown below).

Explanation

Explain the mask digits. The version nibble (13th hex digit) of each GUID, read in order, gives 761217071324305363751746018846348625863340501580338428701418. Exactly this sequence comes out of new Random(228).Next(9): the per-post millisecond seed of the mask generator. The other 30 hex digits of each GUID are Guid.NewGuid() output and carry no message.
Explain the count. Grouped in jan2013-A1: piece A, 9 posts 16-hourly (zone -2); undecided: candidate seeds 162,853,390 / 1,000,996,750, 2 hits vs 0.91 expected; run 39 and Dec Patch-Tuesday boots excluded
Conclusion. Filler. The content is fully explained by the two RNGs.
